I think your channel should be required viewing for all high school students. You're so good at explaining and demonstrating things that primary school students would benefit from watching your videos, along with adult supervision. If I was homeschooling my children, you would definitely be on the list.
@@sreetips do you have a video to get the gold out of smart phones and computer part from start to finish I have about 100lbs of parts and then can you make 14k gold more pure
@@josephandjessicaweber613 Gold is expressed in karats weight. That is 10k is 10 parts gold and 14 parts other metals. 14k gold is 14 parts out of 24 parts with the other 10 parts a combination of other metals such as copper, silver, Nickel or Zinc. These are used in any combination to harden the Gold. 18k is just 18 parts gold and 6 parts other metals and 24k gold is pure Gold. There are several processes but for the do it yourselfer separating them should be easy using the process called Electrolysis. You can look that up by doing a google search. Oh and nothing is 100% in chemistry or science. That is why it only says 99.99% on pure bars of 24k Gold and any chemical that is pure only says 99.99% purity. The only thing that is 100% is death and taxes.
7:55 I really appreciate this description. Chemistry remains one of my weakest fundamental science understandings, despite being exposed to thousands of hours of educational material on or relating to chemistry, metallurgy. It has taken me years to make heads or tails of any of it, but by pure repeat familiarity basically a brute force approach some of the basic principles have started to make sense. It's to sreetips credit that he puts this kind of effort into making these videos. I have probably watched a hundred hours of his content and yet I am still learning something new.
Ionic action on Sreetips! Yeehaw! That stuff looked like silver cement, but it was really silver powder. I love seeing all the different ways silver refining can be done. Alchemy!
The reason for using silver chloride and silver bromide in photography, is the fact they are practically not soluble in water. Silver iodide is also sensitive to light, but as it is very soluble in water, it can't be used in film or photographic paper, as it would be flushed away when touching the developer solution. In your gold refining process, the fact that silver chloride is insoluble in water, lets you filter it out from the chloroauric acid solution. Same salts, but very different things we use these for.
Silver iodide is even less soluble than silver chloride. One of the easy qualitative tests for silver salts is dissolving it, adding chloride to precipitate it, adding ammonium to dissolve it and adding iodide for a yellow precipition. The reason silver iodide isn't used is because it isn't white but bright yellow, interfering with other photochemical processes.
@@apveening True. I made a mistake. I was referring to solubility of silver fluoride, but I mixed things up, relying just on my memory. It is true that the yellow color might be a problem - especially in color film.
Great demonstration. For the amount of silver nitrate in the jar I would not have guessed there would be 9 ounces plus, I suppose that handful of granules would be surprisingly heavy to hold in ones’ hand. Inappropriate comments have been reported. Thank you Sir!👍👍🤟
I work in a lab, and I’ve had to dissolve large quantities of some compounds in small volumes. The impurities left behind are pretty typical because even high purity chemicals have insoluble impurities that becomes more obvious in more concentrated solutions.
10:30 Tap water desinfecting not only with chlorine, but they also use for it hydrogen peroxide and/or ultraviolet-C light. May be your local water supplier use non-chlorine sterilisation method. 15:00 You can filter waste acid solution throгgh slow-flow filter, and freely use it for first time gold refining. 22:15 Make a diluted sirup and slowly (incrementally) add it to silver oxide suspension while mixing it with glass rod P.S.: you may directly smelt silver chloride with baking soda or with caustic soda and get 999 silver. 4AgCl + 4NaHCO3 + t>850°C => 4Ag + 4NaCl + 2H2O↑ + 4CO2↑ + O2↑, (2Ag2O + t>280°C => 4Ag + O2↑) 4AgCl + 2Na2CO3 + t>850°C => 4Ag + 4NaCl + 2CO2↑ + O2↑. Also you may skip silver chloride step, but with sacrifice the high purity of the silver oxide. 2AgNO3 + 2NaOH => Ag2O↓ + 2NaNO3 + H2O, Ag2O + H2O2(any concentration) => 2Ag + H2O + O2↑
Tap water always contains some chloride ions, as even so-called "fresh water" contains a small amounts of NaCl and trace amount of other chlorides. But we don't see any instant "light clouding" of the solution here, and I'm bit surprised by it. I guess it may have something to do with high concentration of AgNO3 solution, but can't point any specific reaction.
@@MrKotBonifacy so I know nothing abt chemistry. We were receiving notices from the state that our water contained too much arsenic, flouride, and uranium. We decided to buy a softner and reverse osmosis. We asked specifically about it's ability to filter out those things and presented them with the notice we were receiving. They said our city water contained more chlorine than most pools, and we could smell it every time we washed clothes or bathed for sure. He said they possibly did that because it would react with the arsenic and we didn't need the special super expensive arsenic filters because of that. Our city ended up with an EDR system for the entire city. We decided to see how well it worked and switched our system to bypass and it was easily noticeable that there was less chlorine smell in the straight water after that. I personally wondered if they cut back on the chlorine due to this new treatment plant we paid for. Maybe his municipality has something similar where they don't havw to use enough chlorine for it react? Idk. I just know the EDR system we got is very unique and seemed extremely effective. Our softner used much much much less salt and our filters on the RO lasted much longer before we had to move away.
@@ford4life069 "Too much arsenic (or uranium)" says nothing about how much it is there, it merely reflects that some ARBITRARILY set "norms" or "limits" are exceeded. Can't really respond to most of what you wrote as there's very little specific data in there. The only thing I'd like to point out is that I was talking about CHLORIDES and CHLORIDE ions - which are "acid parts" in all chloride salts, and that includes the most common salt, i.e "table salt" aka sodium chloride. That "chlorine smell" you're talking about is the result of reaction of elemental CHLORINE (gas) with water, and that produces hypochlorous acid, HClO, or rather hypochlorous anion, ClO-, which has a rather strong and characteristic smell. (Plus probably some other trace amounts of organochlorine compounds which may or may not smell .) Auntie Wiki says: Hypochlorous acid (...) is a weak acid that forms when chlorine dissolves in water, and itself partially dissociates, forming hypochlorite, ClO−. HClO and ClO− are oxidizers, and the primary disinfection agents of chlorine solutions." Newer methods of water disinfection use UV light and ozone, and while it's generally a good idea to use some home purification system for drinking water (that includes water used for cooking), purifying "municipal" water for dishwashing, laundry and other stuff like this is just waste of money, IMO. Also, if you're concerned about uranium or arsenic you should first make some own research on "how much is too much" and "how much it's in 'our' water" - as fearmongering is a favourite tool of all salespeople. And yes, their stuff is ALWAYS GUARANTEED to solve ALL YOUR PROBLEMS - OK, maybe not always, and not all your problems, but CERTAINLY THEIR PROBLEMS with THEIR sales figures. "Caveat emptor", and remember it ain't no silver bullets and neither "cure it all" magic potions. Or Water Purification Systems that will ensure you'll live forever, and in good health too. Also, ion exchange column would be most effective, IMO, for removing any "excess" uranium or arsenic, but frankly I doubt there's so much of it there to be worried, Arsenic contamination is a real problem in SOME parts of Bangladesh, where ground water (i.e. one taken from wells) does indeed contain dangerous levels of arsenic, but that's rather exception. Reverse osmosis is merely a "general tool for removing all dissolved minerals", and the "home stuff" is just as efficient when compared to "industrial stuff" as a spade compared to an excavator. My advice is learn some basic chemistry regarding this issue, so you could actually make some well-informed decisions, and don't rely too much on "general hype and fears", and certainly take all sales pitch with a pinch... no, wait - with a spoonful of salt (yes, the same sodium chloride - substitute for potassium chloride if you suffer from too high blood pressure). And just to give you a simple examples of unsubstantiated "general public hype and fear" - the one about benzene in soft drinks from more that couple of years ago. So there's this benzoic acid and its salt, sodium benzoate, used commonly as food preservative. And it is used also in many "juice-kind" soft drinks, which contains vitamin C, which is a potent reducing agent - and couple of years ago a hype, or ballyhoo was made about the fact that "WAIT! But vitamin C may actually, under specific circumstances, reduce the benzoate anion into free benzene, which is a potent carcinogen!" Oh, yeah, beam me up Scotty... Guess what, regular gasoline does contain SOME benzene too, and if you happen to breathe in, inadvertently, some of those petrol vapours pushed out from nearly empty tank (which happens every time you fill up your car), you probably inhale more benzene that you could POTENTIALLY (and "potentially" is the keyword here) get from a whole year of drinking those soft drink "possibly containing" trace amount of benzene, but surely very unhealthy levels of fructose syrup. Hey, I'm nearly sixty, still alive and kicking (well, to a degree ;-), no cancer (that I know of), and back in my high school times (and that was when sex was safe and chemistry dangerous) I had way more exposure to all benzene, mercury, asbestos and other "it surely will kill ya!" stuff that any contemporary OSHA inspector could imagine (and if he tried he'd probably faint or got heart attack). So "don't worry (too much), be happy" - too much stress or too much "mac-fodder" (washed down with coke) will do you more harm than some trace amounts of uranium or arsenic.
@@MrKotBonifacy TCEQ was sending notices that our city water was above EPA allowable amounts of those chemicals. The city said the water didn't change, the EPA changed their allowable amounts and forced the State of Texas to send out notices and they didn't think they should have to abide by the EPA because it was a small town, abt 1500 people. The people disagreed and the treatment option they chose was this EDR system to bring it into EPA compliance. I can't remember the exact numbers since this was almost a decade ago now. The mass hysteria was limited to this town, the individuals served by those specific wells, even after mixing cleaner wells with the dirtier wells to dilute it closer to what the EPA allowed. My OBGYN also said while we were trying to get pregnant to avoid that water until it was rectified which prompted our getting a system for long term health. Arsenic is apparently cumulative exposure also and we intended to be there much longer than we ended up being. The softner takes out a lot of minerals using the much cheaper salt and allows our basic RO filters to last much longer in the system. The salesman actually didn't take advantage of our concern about the arsenic notices to sell us an overpriced arsenic filter for the RO. He said the city's extremely high chlorine levels in the water changed the arsenic into a different form, some of the chemistry that I don't know, and that allowed it to be taken out by this base level system w/o the specialized expensive arsenic filter. He cld have gotten an extra abt $500 per filter change had he done so. We moved it with us because where we are now tastes like fish shit filled lake water and it is cheaper to buy the softner salt every month than bottled water. Like I said, I don't know the chemistry, I was just making a suggestion on why his water may not have the concentration of whatever it is needed that he expected it to have because I know after the EDR the water went from smelling like you almost stuck your nose in a bottle of bleach to smelling really like not much of anything when we set our system to bypass to see what the quality really was for the money we the citizens had paid for the system. I appreciate the information you included in your response. Thank you.
@@ford4life069 _"the water went from smelling like you almost stuck your nose in a bottle of bleach"_ - yeah, forgot to mention that the regular bleach is (typically) a sodium hypochlorine solution which does the bleaching job (plus some "stabilising" agents), and that's the "hypochlorine" smell. And that's what you get when you chlorinate water "very generously", so to speak. Anyway, seems like the case of that "small Texan town" was rather isolated one, at first I though a regular medium sized town/ city, with proper "industrial sized" water treatment plant taking its water from some river - which was clearly not the case. I guess some wells, especially deep ones may indeed produce very mineral-rich water, so yes, in this case that softener would be a good idea for ALL water used in your household (from what you said I guess it's some sort of sodium cationite based ion exchange column - en.wikipedia.org/wiki/Ion-exchange_resin#Uses). _"where we are now tastes like fish shit filled lake water"_ - sounds like some third world outback... Anyway, that would suggest some poorly treated surface water (i.e. drawn from a lake or a river), but since now you have your own system (which is a good idea under THESE circumstances) you're OK, I guess. Cheers!
Terrifically fascinating! Appreciate the explanation of what kind of chemical reactions were happening. Would be really cool if one could observe what’s going on at the atomic level.
The quality of these videos is phenomenal Sreetips. Thanks for including the chemical equations involved in the process, Shoutout and thankyou to David for helping you with them and for providing the silver nitrate, helps those that are interested gain an understanding of the processes. Excellent video mate bravo, and what a beautiful result.
Nice one Sreetips. You could make sugar soap from the sugar lye waste solution. But you’d likely need to add more sugar since you used a truckload of lye. I found the following on the gold refining forum so as to not use any more materials than I need to: For each troy ounce (31.1) of silver (41.3g of AgCl), it takes 20g of NaOH and 26g white sugar. These figures were proven in a lab. In practice, add 10% extra of each and mix with a stick blender till it turns black. Heating the mixture for faster reaction. Place beaker in a bucket and slowly add sugar. It gets hot and boils over easily. Once the reaction is done it forms Silver Oxide that can be reduced with borax. Use the Volhard titration method to calculate how much ingredients will be needed for 100% conversion. 1.42 ml of water (at least) is required for each gram of expected silver. You can also use only the NaOH to convert the silver chloride to silver oxide and then decompose the silver oxide to silver metal with heat. According to Wikipedia, the decomposition temperature is about 540 ̊F, 292 ̊C.
@@arnedalbakk6315 Hello Arne! I'm up late... thunder storm just popped up. We need the rain here in Dade city Florida. Hope your weather is treating you well.
Cool video Sreetips. It's amazing how much distilled water gose into refining of precious metals. I was doing a small karat scrap run and distilled water appears to be a hot commodity now a days. Normally they're gallons of distilled water lined up on the shelves. It was late and I fell just short on distilled water. So, I ened up taking my tap water and running it through an electric distiller I have.
Does the time and energy input to produce this silver come out cheaper than purchasing the actual silver? I'm interested in this stuff to create my own silver and make coins for barter, but can't tell if it's something I should pursue
@@303sprinklers I’ve thought this after watching some of Sreetips previous videos. A lot of time and materials used for little result. Perhaps it’s more to show the viewer the different processes that may be used. There is also the entertainment value to his subscribers.
Unless someone gets their stuff for free or less than currant prices this is not efficient at all. Tho it would of been more efficient to take cheaper silver and turn it into much more expensive silver nitrate.
@@johnjames5712 yes I know it is not efficient on a monetary scale I meant efficiency as to how much silver is lost in the process compared to the calculated yields as a purely academic exercise
@@chrisharris1522 100% hypothetical yield with no loss in any of the conversions and if none vaporized in the melting process should be about 67.27% pure .999 silver by weight.. so it seems he had a conversation rate of ruffly about 87% efficiency. if my math is close.
Thank you, my teacher, for fixing the translation now, okay, I'm following you now on all your channels, God willing, you are a great man and an expert
Just wanted to say I’ve enjoyed so many of your videos been going thru some thought times the last two years an have spent time watching your videos it’s like meditation I don’t think when I watch your videos so it’s like peace thank you
I was trying to do a cost analysis and it just wasn't adding up to me to make money with a chemical reaction. Everything is real fascinating. I I wish they had stuff like this back when my kids were growing up as children, I never was taught that stuff so I couldn't teach to my own kids if I never do it myself really appreciate the videos.
I’ve only recently started watching - I have no idea why you’re on my feed but I’m glad. One thing I’ve noticed is you’re very careful to not waste any silver resources - always rinsing out with water to scrape every little bit from whatever container 🙂
I remember when i was in eleventh grade Chemistry class back in 1990 the Chemistry did this exact process to show us what you just fid here with Silver Nitrate. He recovered about 35 granms of silver. He kept that piece of silver in a desk drawer. He would pull it out and polish it with some type of polishing rag. It wasn't a week before some student stole it out of his desk. I still remember that.
I graduated back in the 70s. On the last day of school, I stuck around after all the teachers and students had left. It was completely deserted. I spent about half an hour roaming through the empty halls. Past the library, past the cafeteria, down by the pool and the locker rooms. Past all the classrooms. I realized that an important season of my life had passed, and I wanted to savor my last moments in my high school. It was sad and happy at the same time because I knew that I had my whole life ahead of me. Then I walked out the door and never returned to that building ever again. Isn’t it strange how you remember stuff like that?
My personal favourite way to make my AgCl is with KCl. I get that beautiful AgCL and I'm left with some very nice (and fun?) KNO3. Granted I use mine to make more HNO3 but I suppose one could do other things with it if they were so inclined. 😁
For silvering mirrors the reaction is generally reduction of the silver directly from the nitrate. This would be a simpler reaction but it leaves you with nitrated sugar which is an explosion hazard. Your method avoids this hazardous reaction product by removing the nitrate in a separate step. That probably also helps with the purity because any metals with soluble chlorides will remain behind in the first waste. I wonder if you could precipitate the silver with sodium chloride instead of hydrochloric acid, leaving a solution of sodium nitrate.
That was back on December 31st 2022. It was an amazing coincidence that it happened exactly on the last day of the year. The other day I gained one thousand new subscribers in two days. Who knows what drives these things. But I’m grateful for what I’ve been given.
I don't know if you will see this or not. been watching your channel for some time now. enjoy your videos, been doing some refining in silver and gold but mostly silver. Did a refine lately ran through silver cell twice. when poured bar the top of the bar has a lot of, silver crystals in it. why is that wish i could send a picture .thanks for your videos, learned a lot🤗
Hi, Sreetips, I am watching your video for couple of years already, but still I do not do this by myself. And, my question is - would your please create a video and explain what kind of equipment and chemicals I have to have and nice to have to start that kind of hobby? and thank you very much for your videos - they are very informative and intetesting
Sreetips have you seen the recent APPLIED SCIENCE video of the RF tempeture stir bar he has made? Sure looked like a great item to add to your line up to assist you in your reactions.
Hi Mr S....A simpler way to convert AgCl is to put it in a clean Cast Iron Skillet or Pan (no rust), add some 10% H2SO4 and stir (I actually use battery acid at 30%). When the AgCl touches the Clean Iron it will immediately convert to Silver metal.. just keep stirring and after a few mins you will have converted all of the AgCl.. I use this method all the time, it is much safer than the Lye/sugar method. Please give it a try and let us know how you get on.. All the best..
Could you make a video on recovering silver from halides, especially iodide? These are insoluble so I wonder how one should proceed - using excess halide (to dissolve silver halide by pushing solubility equilibrium) or using excess thiosulfate (to complex the silver)?
I just found your channel and find it fascinating. I searched your videos before asking, but have you ever done a video on the equipment I would need to start refining silver and gold? An itemized list would be really nice and then I could set it up and learn while watching your videos. I apologize if I missed it. Thanks again
If there is time he explains everything but please watch out, there many ways to get hurt badly or kill your self. Best thing I can suggest is taking simple classes in chemistry. There is a lot some one needs to know before mixing highly toxic acids. Greetings from Germany.
Very Informative and a fast alternative to the Silver Cell and it's 10 day process. I noticed that you did not do a stannous test on the liquid, after observing the final reaction of the Sugar, you just poured the waste out, However when discarding gold waste you always test for the presents of metal, ,, could there have been any metal in the waste water?
AgNO3 + HCl reaction results in the formation of silver chloride (AgCl) and aqueous nitric acid (HNO3). The balanced chemical equation for the reaction is: AgNO3 + HCl → AgCl + HNO3 This reaction is a double displacement reaction, where the silver ion (Ag+) from silver nitrate (AgNO3) exchanges with the chloride ion (Cl-) from hydrochloric acid (HCl) to form silver chloride (AgCl). The nitrate ion (NO3-) and hydrogen ion (H+) combine to form nitric acid (HNO3). It is important to note that this reaction is a precipitation reaction, where the formation of the insoluble salt silver chloride (AgCl) causes it to precipitate out of the solution. So for every Mol of AgNo3 you need one Mol of HCL. You can not just take the weight of one and think that an equal weight of the other is sufficient. Thus the molar mass of AgNO3 using Avogadro's number 6.022 X 10^23 we get a molar mass for AgNO3 169.87 g/mol and for HCL it is 36.46 g/mol. Now if you have 500g of AgNO3 you would have 500/169.87 = 2.94 mols of AgNO3 and therefore need 2.94 mols of HCL and that would be 2.94 X 36.46 = 107.32g of HCL.
@@sreetips Sir just a random thought.. Would the displacement reaction work in this case with a copper bar to drop the silver? Since the nitrate crystals are dissolved in the solution, are we getting the nitric as well with the distilled water being present and the silver being in ionic form? Is there a way if such a theory can be balanced and executed?
@@Jibrannajam92 Displacement reactions are reactions where one thing is replaced by another. There are many other types of reactions such as addition where something is added and reduction where something is taken away. I don't have the time to explain all the reaction types and what they are used for but if I understand what you are asking is a reaction to remove silver from copper and just have copper as a product then a displacement reaction is not what you want to use. Although it could be used to substitute something else that is easier to remove in a multi step purification.
@@Jibrannajam92 Avogadro's number is a number 6.02 x 10^23 which represents the number of things that make up one Mol of any substance. So yes NaOH, sugar and any other compound or element in a quantity of one Mol will have 6.02 x 10^ 23 parts.
Fantastic video - just a question, why can't you use something like sodium chloride (table salt) to precipitate out the silver chloride instead of hydrochloric acid?
@@sreetips Cool - thank you for the reply. I guess the activity of the hydrochloric acid is far better than normal salt solution. Probably avoids passivation of the surfaces as well to allow the precipitation to go to completion.
maybe your tap water has a low amount of chlorine(most likely only normal salt and some calcium salts if it is a membrane system) in is and/or they use ozone instead of the chlorine since it is easier to get as it can be produced on site from an ozone generator system. i think that is the reason there was a low reaction when you added the tap water, i dont know for sure but i think it had a very small cloudiness to it but my eyes/screen can be playing tricks on me.
Is it possible to do a video on refining silver chloride? Many have made so many mistakes and create silver chloride containing lost gold. Some low quality bottled water labed distilled can make bad outcomes. Thanks
I just did that trying to make a reference standard. Somebody had refilled my water bottle with tap water. Silver chloride appears impossible to redissolve in an acid environment or at least I couldn’t do it.
Sreetips!! Huge fan here man. I don't know much about what you do, but I got a idea watching this. The whole time you were using the hand blender I was cringing at the beaker vibrating all over. That's gotta be tough on the beaker and your ears. Here's my idea.... Use a old computer mousepad, or a piece of toolbox "no slip" drawer liner between the beaker and the casserole dish. I bet it's worth the try!
I think the "trash" in your silver nitrate solution is just silver. As you said, light has interacted with the crystals and allowed some of the nitrogen to release.
That was a really good video, great for education, ... I do have a quick question, after you disolve the silver nitrate in the water, could you just put in a copper plate to draw out the pure silver metal instead of doing all that rinsing with chemicals and sugar? Or am I missing something here? I've see people draw the silver out with copper, then rinse, then make the ingot. I used to make silver nitrate myself with lots of rinsing involved but there is no short cut for that one, but thought there might be for this one. Thanks for sharing and look forward to your reply on this.
Yes, if you add a few drops of nitric acid (a little free nitric is required for the silver to react and come down). But it won’t be high purity silver. Very close, but the only way to be sure is to melt it and run it through the silver cell.
Time stamp 10.35, tap water has very minimal amounts of chlorine. In most areas, it's not detectable. This also depends on your area's water sanitation system. A lot of city/county systems are less reliant on chemical sanitation methods now and utilize a series of mechanical filtrations, heat, and light to sanitize the tap water. That said, I still treat my tap water for chlorine before adding it to my aquarium. I'm not surprised there wasn't a reaction.
There’s plenty of chlorine in the tap water. It’s highly detectable when I rinse a flask that has traces of silver nitrate. I think that it had something to do with the highly concentrated silver nitrate solution. Baffling.
I imagine it can fluctuate. I drank a glass of tap water about 2 weeks ago, NSW Australia, and it tasted like a lap pool. Next day, and since, it was and has been fine.
i assure you, a chlorine gas solution is still VERY widely used to treat drinking water. a certain limit has to leave those plants and sample sites are located around the city and are tested every day to confirm a parameter is met....
It should be noted that not all "Distilled Waters" found in Walmart, K-mart, etc are created equal. I once tested Distilled water from walmart, and it was clearly not true distilled water. It was clearly re-mineralized. As distilled water is non conductive. A mere 9V battery should not cause a reaction lol It may be purified via distillation, however.
Turn your torch off your mold when you pour 🫗. You'll avoid the "bar scorching" and also avoid "water ripples" in the bar after the pour. All in all, very enjoyable 😉
The flame prevents air from contacting the surface as the silver freezes. Without the flame the surface would be frosty instead of a bright shiny mirror-like finish.
I like the ripples. I watch a metal recycling gentleman out of Australia and his aluminum, brass, zinc, copper, etc reclamation videos. His bars always have a dull and dirty appearance to them. He puts them onto ice blocks from his rain buckets and they shine up a good bit from that but he has to polish them to get a shine like what Mr Sreetips gets. He's looking to learn how to extract the precious metals out of some of the components that are inside the things he recycles so I told him abt this channel in his comments. Idk if he wants to do caustic chemicals - that wouod scare me to try on my own without an experienced eye teaching me and warning me of my own mistakes - but I think most folks wld stand a good chance learning from this channel for sure if they had the courage. I could get as far as melting purchased jewelry and pouring it into a tradeable size, but purifying is above my comfort level. I love watching it though. I'm still hoping to catch something on ebay I can afford just to have because it's beautiful. 💜
@sreetips lol I polish and buff after that's why I said that 😅. Sorry for the misunderstanding (you were not in my head when that post came to mind and didn't know my thinking hahaha) .. if you ever do start polishing down the bars, turn the fire stream as low as you feel comfortable and have minimal scorching for when you're polishing afterwards 😉
Sreetips, thank you for the video! Random thought, can you premiere your videos and add a live chat with super chat? Whatever is the best way for you to make money off of your content, when it comes down to it.... Live chats and influencer engagement is a great time though! Plus I am sure there are alot of questions related to refining and unrelated as well that your followers may have.
Interesting experiment.. However after doing some research I found 500g of Silver nitrate is at least $1,300 to $2,000+.. Where as I can purchase 50 ounces of pure silver for about $1400 - $1500 Just buying it outright.. What am I missing? Again great video & good explanations for not being a chemist.
The silver nitrate was donated to me. I agreed to convert it to pure metal for the donor. He gets a nice silver bar, I get the video. Win-win. I can make high purity silver nitrate by dissolving some of my silver crystal in hot dilute nitric acid.
you are a great person i am enjoying your technique and your talent , plz help me for solving my problem the silver chloride dehydrated before i do the next step using caustic soda and table sugar to get silver metal..what can i do to restore my silver ?
I’ve never processed dry silver chloride. Harold_V (on the goldrefiningforum.com) said that he was able to reduce the dry silver chloride in a crucible with sodium carbonate in a gas furnace. But very never tried it,
This is my hobby. I’m not a professional refiner. I only work on material that my wife and I find at local sales. Someone once said, “if you turn your hobby into your work, then it becomes just that, work.”
Keep the flame of your oxy torch high enough that the blue inner cone of the flame does not touch the silver. Even though silver does not oxidize easily, there will be a small amount - and it will increase the amount of absorbed oxygen that causes bubbles/pits in the cooling ingot. The outer flame is a reducing flame and will minimize any oxygen effects.
Other options are using zinc and sulfuric acid (National Research Council. Prudent practices for disposal of chemicals from lab oratories. 1983.) or ammonia and hydrogen peroxide. High purity silver can be obtained by treating the oxide with hydrogen at about 150 oC.
Top notch channel sir!! I have a Question.. If the lye wasn't sufficient before the suger was added (silver oxide remains in my solution ), can I go back to the lye or???? Any help is appreciated.
I just converted silver nitrate into silver metal last week and have already made jewelry out of some of it, of course I got a bit of it on my skin and have the brown spots but not too badly.😁
Believe me, scrub the stains with hydrogen peroxide. I found out by accident that this works amazingly well. Won’t get it off 100% but sure looks better than wearing those stains for a week and a half.
This is actually really fascinating. Do you (or if any fans who see this and know if he does) have a list of all the various equipment and if needed brands to do the process from start to finish?
Where are you getting the silver nitrate? Assuming that bottle was 1/2 full ( 250 g) the current price of S-181Fisher Scientific silver nitrate is $9,000 USD per 500g so roughly $4,500 worth Spot silver is currently $25.00 usd per OZ 25 x 9 oz = $225.00 ? or am I missing something?
That bottle was very close to full, but I didn’t weigh it before I started, should have. It was donated by a chemist who shut down his lab. I gave the silver bar back to him the next day. I could easily dissolve some of my pure silver crystal in nitric, evaporate off the liquid in a desiccated, and make high purity silver nitrate. Or I could re-dissolve that bar and do the same. But I’ve already given it to the chemist.
I was wondering if this process could be used for sterling silver, like you did in your video, “Silver refining with household chemicals”. If so, and I used nitric to dissolve sterling, I could use HCl or sea salt for precipitation correct? Also, how would I neutralize the waste for disposal? I know I use angle iron for the copper nitrate but is that all that is needed? Or am I way off base completely lol. Love your videos man. Been on a binge for a hot minute 😊
At todays spot price for silver this final bar would be $228.78 As an avid stacker of silver bullion I ask …….. is this process, with all the costs of materials used, including the original silver nitrate, wouldn’t this process cost more than just purchasing silver bullion?
@@patriotsouthern8123 Because that silver nitrate was made with mined silver. The silver has to come from somewhere and that always is mines (even if you have to trace it back a couple of millennia).

@@sreetips do you have a video to get the gold out of smart phones and computer part from start to finish I have about 100lbs of parts and then can you make 14k gold more pure
@@josephandjessicaweber613 Gold is expressed in karats weight. That is 10k is 10 parts gold and 14 parts other metals. 14k gold is 14 parts out of 24 parts with the other 10 parts a combination of other metals such as copper, silver, Nickel or Zinc. These are used in any combination to harden the Gold. 18k is just 18 parts gold and 6 parts other metals and 24k gold is pure Gold. There are several processes but for the do it yourselfer separating them should be easy using the process called Electrolysis. You can look that up by doing a google search. Oh and nothing is 100% in chemistry or science. That is why it only says 99.99% on pure bars of 24k Gold and any chemical that is pure only says 99.99% purity. The only thing that is 100% is death and taxes.
@@Zonfeair so how could you make let's say 14k gold more pure the reason I ask is I have about 30lbs of 14k gold
7:55 I really appreciate this description. Chemistry remains one of my weakest fundamental science understandings, despite being exposed to thousands of hours of educational material on or relating to chemistry, metallurgy. It has taken me years to make heads or tails of any of it, but by pure repeat familiarity basically a brute force approach some of the basic principles have started to make sense. It's to sreetips credit that he puts this kind of effort into making these videos. I have probably watched a hundred hours of his content and yet I am still learning something new.
This is exactly what I needed tonight! Sreetips videos are the most satisfying thing after a long day at work
Excellent video it's nice to know the formulas for each reaction. Absolutely beautiful silver bar.

Your reaction is balanced. No blast is coming... This is my third favorite reaction that you do on this channel.
Not gonna lie that made me giggle.
Really a fantastic video! I loved seeing the chemical reactions written out in formula! Does help in comprehension of the entire process.
Ionic action on Sreetips! Yeehaw! That stuff looked like silver cement, but it was really silver powder. I love seeing all the different ways silver refining can be done. Alchemy!
The reason for using silver chloride and silver bromide in photography, is the fact they are practically not soluble in water. Silver iodide is also sensitive to light, but as it is very soluble in water, it can't be used in film or photographic paper, as it would be flushed away when touching the developer solution. In your gold refining process, the fact that silver chloride is insoluble in water, lets you filter it out from the chloroauric acid solution. Same salts, but very different things we use these for.
@@IsawSREETIPStouchaLITTLEBOYina ah, ok. You're one of those. That explains your disgusting comments...
Silver iodide is even less soluble than silver chloride. One of the easy qualitative tests for silver salts is dissolving it, adding chloride to precipitate it, adding ammonium to dissolve it and adding iodide for a yellow precipition.
The reason silver iodide isn't used is because it isn't white but bright yellow, interfering with other photochemical processes.
@@apveening True. I made a mistake. I was referring to solubility of silver fluoride, but I mixed things up, relying just on my memory. It is true that the yellow color might be a problem - especially in color film.
I'm not sure what form of silver is used, but it is used in lenses for photo-grade eyewear.
@@b6983832 To err is human.
Great demonstration. For the amount of silver nitrate in the jar I would not have guessed there would be 9 ounces plus, I suppose that handful of granules would be surprisingly heavy to hold in ones’ hand. Inappropriate comments have been reported. Thank you Sir!👍👍🤟
I work in a lab, and I’ve had to dissolve large quantities of some compounds in small volumes. The impurities left behind are pretty typical because even high purity chemicals have insoluble impurities that becomes more obvious in more concentrated solutions.
That makes sense.
10:30 Tap water desinfecting not only with chlorine, but they also use for it hydrogen peroxide and/or ultraviolet-C light. May be your local water supplier use non-chlorine sterilisation method.
15:00 You can filter waste acid solution throгgh slow-flow filter, and freely use it for first time gold refining.
22:15 Make a diluted sirup and slowly (incrementally) add it to silver oxide suspension while mixing it with glass rod
P.S.: you may directly smelt silver chloride with baking soda or with caustic soda and get 999 silver.
4AgCl + 4NaHCO3 + t>850°C => 4Ag + 4NaCl + 2H2O↑ + 4CO2↑ + O2↑, (2Ag2O + t>280°C => 4Ag + O2↑)
4AgCl + 2Na2CO3 + t>850°C => 4Ag + 4NaCl + 2CO2↑ + O2↑.
Also you may skip silver chloride step, but with sacrifice the high purity of the silver oxide.
2AgNO3 + 2NaOH => Ag2O↓ + 2NaNO3 + H2O, Ag2O + H2O2(any concentration) => 2Ag + H2O + O2↑
Tap water always contains some chloride ions, as even so-called "fresh water" contains a small amounts of NaCl and trace amount of other chlorides. But we don't see any instant "light clouding" of the solution here, and I'm bit surprised by it. I guess it may have something to do with high concentration of AgNO3 solution, but can't point any specific reaction.
@@MrKotBonifacy so I know nothing abt chemistry. We were receiving notices from the state that our water contained too much arsenic, flouride, and uranium. We decided to buy a softner and reverse osmosis. We asked specifically about it's ability to filter out those things and presented them with the notice we were receiving. They said our city water contained more chlorine than most pools, and we could smell it every time we washed clothes or bathed for sure. He said they possibly did that because it would react with the arsenic and we didn't need the special super expensive arsenic filters because of that. Our city ended up with an EDR system for the entire city. We decided to see how well it worked and switched our system to bypass and it was easily noticeable that there was less chlorine smell in the straight water after that. I personally wondered if they cut back on the chlorine due to this new treatment plant we paid for. Maybe his municipality has something similar where they don't havw to use enough chlorine for it react? Idk. I just know the EDR system we got is very unique and seemed extremely effective. Our softner used much much much less salt and our filters on the RO lasted much longer before we had to move away.
@@ford4life069 "Too much arsenic (or uranium)" says nothing about how much it is there, it merely reflects that some ARBITRARILY set "norms" or "limits" are exceeded. Can't really respond to most of what you wrote as there's very little specific data in there. The only thing I'd like to point out is that I was talking about CHLORIDES and CHLORIDE ions - which are "acid parts" in all chloride salts, and that includes the most common salt, i.e "table salt" aka sodium chloride.
That "chlorine smell" you're talking about is the result of reaction of elemental CHLORINE (gas) with water, and that produces hypochlorous acid, HClO, or rather hypochlorous anion, ClO-, which has a rather strong and characteristic smell. (Plus probably some other trace amounts of organochlorine compounds which may or may not smell .)
Auntie Wiki says:
Hypochlorous acid (...) is a weak acid that forms when chlorine dissolves in water, and itself partially dissociates, forming hypochlorite, ClO−. HClO and ClO− are oxidizers, and the primary disinfection agents of chlorine solutions."
Newer methods of water disinfection use UV light and ozone, and while it's generally a good idea to use some home purification system for drinking water (that includes water used for cooking), purifying "municipal" water for dishwashing, laundry and other stuff like this is just waste of money, IMO. Also, if you're concerned about uranium or arsenic you should first make some own research on "how much is too much" and "how much it's in 'our' water" - as fearmongering is a favourite tool of all salespeople. And yes, their stuff is ALWAYS GUARANTEED to solve ALL YOUR PROBLEMS - OK, maybe not always, and not all your problems, but CERTAINLY THEIR PROBLEMS with THEIR sales figures. "Caveat emptor", and remember it ain't no silver bullets and neither "cure it all" magic potions. Or Water Purification Systems that will ensure you'll live forever, and in good health too.
Also, ion exchange column would be most effective, IMO, for removing any "excess" uranium or arsenic, but frankly I doubt there's so much of it there to be worried, Arsenic contamination is a real problem in SOME parts of Bangladesh, where ground water (i.e. one taken from wells) does indeed contain dangerous levels of arsenic, but that's rather exception.
Reverse osmosis is merely a "general tool for removing all dissolved minerals", and the "home stuff" is just as efficient when compared to "industrial stuff" as a spade compared to an excavator.
My advice is learn some basic chemistry regarding this issue, so you could actually make some well-informed decisions, and don't rely too much on "general hype and fears", and certainly take all sales pitch with a pinch... no, wait - with a spoonful of salt (yes, the same sodium chloride - substitute for potassium chloride if you suffer from too high blood pressure).
And just to give you a simple examples of unsubstantiated "general public hype and fear" - the one about benzene in soft drinks from more that couple of years ago. So there's this benzoic acid and its salt, sodium benzoate, used commonly as food preservative. And it is used also in many "juice-kind" soft drinks, which contains vitamin C, which is a potent reducing agent - and couple of years ago a hype, or ballyhoo was made about the fact that "WAIT! But vitamin C may actually, under specific circumstances, reduce the benzoate anion into free benzene, which is a potent carcinogen!" Oh, yeah, beam me up Scotty... Guess what, regular gasoline does contain SOME benzene too, and if you happen to breathe in, inadvertently, some of those petrol vapours pushed out from nearly empty tank (which happens every time you fill up your car), you probably inhale more benzene that you could POTENTIALLY (and "potentially" is the keyword here) get from a whole year of drinking those soft drink "possibly containing" trace amount of benzene, but surely very unhealthy levels of fructose syrup.
Hey, I'm nearly sixty, still alive and kicking (well, to a degree ;-), no cancer (that I know of), and back in my high school times (and that was when sex was safe and chemistry dangerous) I had way more exposure to all benzene, mercury, asbestos and other "it surely will kill ya!" stuff that any contemporary OSHA inspector could imagine (and if he tried he'd probably faint or got heart attack).
So "don't worry (too much), be happy" - too much stress or too much "mac-fodder" (washed down with coke) will do you more harm than some trace amounts of uranium or arsenic.
@@MrKotBonifacy TCEQ was sending notices that our city water was above EPA allowable amounts of those chemicals. The city said the water didn't change, the EPA changed their allowable amounts and forced the State of Texas to send out notices and they didn't think they should have to abide by the EPA because it was a small town, abt 1500 people. The people disagreed and the treatment option they chose was this EDR system to bring it into EPA compliance. I can't remember the exact numbers since this was almost a decade ago now. The mass hysteria was limited to this town, the individuals served by those specific wells, even after mixing cleaner wells with the dirtier wells to dilute it closer to what the EPA allowed. My OBGYN also said while we were trying to get pregnant to avoid that water until it was rectified which prompted our getting a system for long term health. Arsenic is apparently cumulative exposure also and we intended to be there much longer than we ended up being. The softner takes out a lot of minerals using the much cheaper salt and allows our basic RO filters to last much longer in the system.
The salesman actually didn't take advantage of our concern about the arsenic notices to sell us an overpriced arsenic filter for the RO. He said the city's extremely high chlorine levels in the water changed the arsenic into a different form, some of the chemistry that I don't know, and that allowed it to be taken out by this base level system w/o the specialized expensive arsenic filter. He cld have gotten an extra abt $500 per filter change had he done so. We moved it with us because where we are now tastes like fish shit filled lake water and it is cheaper to buy the softner salt every month than bottled water.
Like I said, I don't know the chemistry, I was just making a suggestion on why his water may not have the concentration of whatever it is needed that he expected it to have because I know after the EDR the water went from smelling like you almost stuck your nose in a bottle of bleach to smelling really like not much of anything when we set our system to bypass to see what the quality really was for the money we the citizens had paid for the system.
I appreciate the information you included in your response. Thank you.
@@ford4life069 _"the water went from smelling like you almost stuck your nose in a bottle of bleach"_ - yeah, forgot to mention that the regular bleach is (typically) a sodium hypochlorine solution which does the bleaching job (plus some "stabilising" agents), and that's the "hypochlorine" smell. And that's what you get when you chlorinate water "very generously", so to speak.
Anyway, seems like the case of that "small Texan town" was rather isolated one, at first I though a regular medium sized town/ city, with proper "industrial sized" water treatment plant taking its water from some river - which was clearly not the case.
I guess some wells, especially deep ones may indeed produce very mineral-rich water, so yes, in this case that softener would be a good idea for ALL water used in your household (from what you said I guess it's some sort of sodium cationite based ion exchange column - en.wikipedia.org/wiki/Ion-exchange_resin#Uses).
_"where we are now tastes like fish shit filled lake water"_ - sounds like some third world outback... Anyway, that would suggest some poorly treated surface water (i.e. drawn from a lake or a river), but since now you have your own system (which is a good idea under THESE circumstances) you're OK, I guess. Cheers!
Interesting to see this shown in detail. Thanks for taking the time to share with us. The end result of the bar looked very nice with the lines.
Terrifically fascinating! Appreciate the explanation of what kind of chemical reactions were happening. Would be really cool if one could observe what’s going on at the atomic level.

Excellent video mate bravo, and what a beautiful result.
Nice one Sreetips. You could make sugar soap from the sugar lye waste solution. But you’d likely need to add more sugar since you used a truckload of lye.
I found the following on the gold refining forum so as to not use any more materials than I need to: For each troy ounce (31.1) of silver (41.3g of AgCl), it takes 20g of NaOH and 26g white sugar. These figures were proven in a lab. In practice, add 10% extra of each and mix with a stick blender till it turns black. Heating the mixture for faster reaction. Place beaker in a bucket and slowly add sugar. It gets hot and boils over easily. Once the reaction is done it forms Silver Oxide that can be reduced with borax. Use the Volhard titration method to calculate how much ingredients will be needed for 100% conversion. 1.42 ml of water (at least) is required for each gram of expected silver. You can also use only the NaOH to convert the silver chloride to silver oxide and then decompose the silver oxide to silver metal with heat. According to Wikipedia, the decomposition temperature is about 540 ̊F, 292 ̊C.
Nice

Unless someone gets their stuff for free or less than currant prices this is not efficient at all. Tho it would of been more efficient to take cheaper silver and turn it into much more expensive silver nitrate.
@@johnjames5712 yes I know it is not efficient on a monetary scale I meant efficiency as to how much silver is lost in the process compared to the calculated yields as a purely academic exercise
@@chrisharris1522 100% hypothetical yield with no loss in any of the conversions and if none vaporized in the melting process should be about 67.27% pure .999 silver by weight.. so it seems he had a conversation rate of ruffly about 87% efficiency. if my math is close.

Hello Mrs and Mr sreetips. What a stunning clip.
I realy enjoy it. Thank you sir😊. Arne
I remember when i was in eleventh grade Chemistry class back in 1990 the Chemistry did this exact process to show us what you just fid here with Silver Nitrate. He recovered about 35 granms of silver. He kept that piece of silver in a desk drawer. He would pull it out and polish it with some type of polishing rag. It wasn't a week before some student stole it out of his desk. I still remember that.
I graduated back in the 70s. On the last day of school, I stuck around after all the teachers and students had left. It was completely deserted. I spent about half an hour roaming through the empty halls. Past the library, past the cafeteria, down by the pool and the locker rooms. Past all the classrooms. I realized that an important season of my life had passed, and I wanted to savor my last moments in my high school. It was sad and happy at the same time because I knew that I had my whole life ahead of me. Then I walked out the door and never returned to that building ever again. Isn’t it strange how you remember stuff like that?
My personal favourite way to make my AgCl is with KCl. I get that beautiful AgCL and I'm left with some very nice (and fun?) KNO3. Granted I use mine to make more HNO3 but I suppose one could do other things with it if they were so inclined. 😁
As an old mining geochemist, I approve this statement. 😂😂😂
...e.g. making nitrite from nitrate - very interesting chemistry and useful compound for various indicators (e.g. cobaltinitrite)
Given 50lb bags of kcl for water softeners this is way cheaper than hcl.
@@lrmackmcbride7498 Exactly. I pay $22 for a 25kg bag of KCl or $20 for a gallon jug of HCl.
Very interesting and informative video thank you for sharing this six stars
For silvering mirrors the reaction is generally reduction of the silver directly from the nitrate. This would be a simpler reaction but it leaves you with nitrated sugar which is an explosion hazard.
Your method avoids this hazardous reaction product by removing the nitrate in a separate step. That probably also helps with the purity because any metals with soluble chlorides will remain behind in the first waste.
I wonder if you could precipitate the silver with sodium chloride instead of hydrochloric acid, leaving a solution of sodium nitrate.
Yes, sodium chloride will also work

Hi Mr S....A simpler way to convert AgCl is to put it in a clean Cast Iron Skillet or Pan (no rust), add some 10% H2SO4 and stir (I actually use battery acid at 30%). When the AgCl touches the Clean Iron it will immediately convert to Silver metal.. just keep stirring and after a few mins you will have converted all of the AgCl..
I use this method all the time, it is much safer than the Lye/sugar method.
Please give it a try and let us know how you get on..
All the best..

Very Informative and a fast alternative to the Silver Cell and it's 10 day process. I noticed that you did not do a stannous test on the liquid, after observing the final reaction of the Sugar, you just poured the waste out, However when discarding gold waste you always test for the presents of metal, ,, could there have been any metal in the waste water?
Possibly
That was definitely a first!!
Loved the process and the bar!!!
AgNO3 + HCl reaction results in the formation of silver chloride (AgCl) and aqueous nitric acid (HNO3).
The balanced chemical equation for the reaction is:
AgNO3 + HCl → AgCl + HNO3
This reaction is a double displacement reaction, where the silver ion (Ag+) from silver nitrate (AgNO3) exchanges with the chloride ion (Cl-) from hydrochloric acid (HCl) to form silver chloride (AgCl). The nitrate ion (NO3-) and hydrogen ion (H+) combine to form nitric acid (HNO3).
It is important to note that this reaction is a precipitation reaction, where the formation of the insoluble salt silver chloride (AgCl) causes it to precipitate out of the solution. So for every Mol of AgNo3 you need one Mol of HCL. You can not just take the weight of one and think that an equal weight of the other is sufficient. Thus the molar mass of AgNO3 using Avogadro's number 6.022 X 10^23 we get a molar mass for AgNO3 169.87 g/mol and for HCL it is 36.46 g/mol. Now if you have 500g of AgNO3 you would have 500/169.87 = 2.94 mols of AgNO3 and therefore need 2.94 mols of HCL and that would be 2.94 X 36.46 = 107.32g of HCL.
Excellent, thank you
WOW! This comment just blew me! Can the Avogadro's number be used for the other compounds such as NaOH and Sugar as well?
@@sreetips Sir just a random thought.. Would the displacement reaction work in this case with a copper bar to drop the silver? Since the nitrate crystals are dissolved in the solution, are we getting the nitric as well with the distilled water being present and the silver being in ionic form? Is there a way if such a theory can be balanced and executed?
@@Jibrannajam92 Displacement reactions are reactions where one thing is replaced by another. There are many other types of reactions such as addition where something is added and reduction where something is taken away. I don't have the time to explain all the reaction types and what they are used for but if I understand what you are asking is a reaction to remove silver from copper and just have copper as a product then a displacement reaction is not what you want to use. Although it could be used to substitute something else that is easier to remove in a multi step purification.
@@Jibrannajam92 Avogadro's number is a number 6.02 x 10^23 which represents the number of things that make up one Mol of any substance. So yes NaOH, sugar and any other compound or element in a quantity of one Mol will have 6.02 x 10^ 23 parts.
I really liked this video it's something I've not seen yet thanks Sreetips for the video.
Fantastic video - just a question, why can't you use something like sodium chloride (table salt) to precipitate out the silver chloride instead of hydrochloric acid?
You can
Salt water will give nearly the same reaction.
@@sreetips Cool - thank you for the reply. I guess the activity of the hydrochloric acid is far better than normal salt solution. Probably avoids passivation of the surfaces as well to allow the precipitation to go to completion.
Adding hydrochloric acid is much easier for me. There are extra steps for salt.
Now i knowwhat to do exactly to my silver cloride i get out of the palladuim and gold thanks screetips nice job so cleanly done
maybe your tap water has a low amount of chlorine(most likely only normal salt and some calcium salts if it is a membrane system) in is and/or they use ozone instead of the chlorine since it is easier to get as it can be produced on site from an ozone generator system. i think that is the reason there was a low reaction when you added the tap water, i dont know for sure but i think it had a very small cloudiness to it but my eyes/screen can be playing tricks on me.
Besides that, chlorine (gas, in this case dissolved in water) is pretty low in free chloride ions to precipitate with the silver.
Love these videos, I still need to grab a few grams on that gold powder if it's still around
I sold the last two grams the other day. I’ll do another batch and get some listed. I’m exhausted.
Is it possible to do a video on refining silver chloride? Many have made so many mistakes and create silver chloride containing lost gold. Some low quality bottled water labed distilled can make bad outcomes. Thanks
I just did that trying to make a reference standard. Somebody had refilled my water bottle with tap water. Silver chloride appears impossible to redissolve in an acid environment or at least I couldn’t do it.
Silver chloride is insoluble in acid. Best to filter it out.
Sreetips!! Huge fan here man. I don't know much about what you do, but I got a idea watching this. The whole time you were using the hand blender I was cringing at the beaker vibrating all over. That's gotta be tough on the beaker and your ears. Here's my idea.... Use a old computer mousepad, or a piece of toolbox "no slip" drawer liner between the beaker and the casserole dish. I bet it's worth the try!
That’s a good idea, thank you
I think the "trash" in your silver nitrate solution is just silver. As you said, light has interacted with the crystals and allowed some of the nitrogen to release.
That was a really good video, great for education, ... I do have a quick question, after you disolve the silver nitrate in the water, could you just put in a copper plate to draw out the pure silver metal instead of doing all that rinsing with chemicals and sugar? Or am I missing something here? I've see people draw the silver out with copper, then rinse, then make the ingot. I used to make silver nitrate myself with lots of rinsing involved but there is no short cut for that one, but thought there might be for this one. Thanks for sharing and look forward to your reply on this.
Yes, if you add a few drops of nitric acid (a little free nitric is required for the silver to react and come down). But it won’t be high purity silver. Very close, but the only way to be sure is to melt it and run it through the silver cell.
@Sreetips
Did you weigh the Silver Nitrate to come up with a yield?
Very informative video!

That was cool as hell
College: "Are you majoring in chemistry because of Beaking Bad?"
Me: .> .... "Yes."
🤣😂🤣😂🤣😂😎👍
Time stamp 10.35, tap water has very minimal amounts of chlorine. In most areas, it's not detectable. This also depends on your area's water sanitation system. A lot of city/county systems are less reliant on chemical sanitation methods now and utilize a series of mechanical filtrations, heat, and light to sanitize the tap water. That said, I still treat my tap water for chlorine before adding it to my aquarium. I'm not surprised there wasn't a reaction.
There’s plenty of chlorine in the tap water. It’s highly detectable when I rinse a flask that has traces of silver nitrate. I think that it had something to do with the highly concentrated silver nitrate solution. Baffling.
I imagine it can fluctuate. I drank a glass of tap water about 2 weeks ago, NSW Australia, and it tasted like a lap pool. Next day, and since, it was and has been fine.
i assure you, a chlorine gas solution is still VERY widely used to treat drinking water. a certain limit has to leave those plants and sample sites are located around the city and are tested every day to confirm a parameter is met....
It should be noted that not all "Distilled Waters" found in Walmart, K-mart, etc are created equal. I once tested Distilled water from walmart, and it was clearly not true distilled water. It was clearly re-mineralized. As distilled water is non conductive. A mere 9V battery should not cause a reaction lol
It may be purified via distillation, however.
Excelente,ótimo trabalho.
Brilliant video…that silver nitrate powder looked very old.
Probably was
That's really cool, congrats David and thanks Sreetips
Turn your torch off your mold when you pour 🫗. You'll avoid the "bar scorching" and also avoid "water ripples" in the bar after the pour. All in all, very enjoyable 😉
The flame prevents air from contacting the surface as the silver freezes. Without the flame the surface would be frosty instead of a bright shiny mirror-like finish.
I like the ripples. I watch a metal recycling gentleman out of Australia and his aluminum, brass, zinc, copper, etc reclamation videos. His bars always have a dull and dirty appearance to them. He puts them onto ice blocks from his rain buckets and they shine up a good bit from that but he has to polish them to get a shine like what Mr Sreetips gets. He's looking to learn how to extract the precious metals out of some of the components that are inside the things he recycles so I told him abt this channel in his comments. Idk if he wants to do caustic chemicals - that wouod scare me to try on my own without an experienced eye teaching me and warning me of my own mistakes - but I think most folks wld stand a good chance learning from this channel for sure if they had the courage. I could get as far as melting purchased jewelry and pouring it into a tradeable size, but purifying is above my comfort level. I love watching it though. I'm still hoping to catch something on ebay I can afford just to have because it's beautiful. 💜
@sreetips lol I polish and buff after that's why I said that 😅. Sorry for the misunderstanding (you were not in my head when that post came to mind and didn't know my thinking hahaha) .. if you ever do start polishing down the bars, turn the fire stream as low as you feel comfortable and have minimal scorching for when you're polishing afterwards 😉
Sreetips, thank you for the video!
Random thought, can you premiere your videos and add a live chat with super chat? Whatever is the best way for you to make money off of your content, when it comes down to it....
Live chats and influencer engagement is a great time though!
Plus I am sure there are alot of questions related to refining and unrelated as well that your followers may have.
I’m still totally unfamiliar with how all that works. This is my hobby and the simpler the better.
Perhaps deionized water instead of distilled water for this application?
Interesting experiment.. However after doing some research I found 500g of Silver nitrate is at least $1,300 to $2,000+.. Where as I can purchase 50 ounces of pure silver for about $1400 - $1500 Just buying it outright.. What am I missing? Again great video & good explanations for not being a chemist.
The silver nitrate was donated to me. I agreed to convert it to pure metal for the donor. He gets a nice silver bar, I get the video. Win-win. I can make high purity silver nitrate by dissolving some of my silver crystal in hot dilute nitric acid.
@@sreetips Thank you for the response.
Bravo.........flash powder........hard to get the stuff know days...........stump remover ......no silver......I'm into plateing.....cheers
Out of curiosity, how do you know the resulting silver is .999 without an assay?
Twelve years experience and thousands of ounces refined.
you are a great person i am enjoying your technique and your talent , plz help me for solving my problem the silver chloride dehydrated before i do the next step using caustic soda and table sugar to get silver metal..what can i do to restore my silver ?
I’ve never processed dry silver chloride. Harold_V (on the goldrefiningforum.com) said that he was able to reduce the dry silver chloride in a crucible with sodium carbonate in a gas furnace. But very never tried it,
This is fascinating, and I’d love to find a way to make this a hobby of mine and even a career.
This is my hobby. I’m not a professional refiner. I only work on material that my wife and I find at local sales. Someone once said, “if you turn your hobby into your work, then it becomes just that, work.”
Try sulfuric acid and a few iron nails. In my personal opinion its faster and less washing time.
Thanks for the tip
Keep the flame of your oxy torch high enough that the blue inner cone of the flame does not touch the silver. Even though silver does not oxidize easily, there will be a small amount - and it will increase the amount of absorbed oxygen that causes bubbles/pits in the cooling ingot. The outer flame is a reducing flame and will minimize any oxygen effects.
Good to know, thank you.
That makes me feel better that I'm not the only one to make a silver volcano! Lol
39:00 what a beautiful end product
Other options are using zinc and sulfuric acid (National Research Council. Prudent practices for disposal of chemicals from lab oratories. 1983.) or ammonia and hydrogen peroxide. High purity silver can be obtained by treating the oxide with hydrogen at about 150 oC.
Top notch channel sir!!
I have a Question..
If the lye wasn't sufficient before the suger was added (silver oxide remains in my solution ), can I go back to the lye or???? Any help is appreciated.
Possibly, but I’ve never tried that.
🎶 Just a spoonful of sugar helps the silver precipitate, silver precipitate. 🎶
The nitrate reagent is considerably more valuable than any recovered metal.
I can make reagent grade silver nitrate.
I just converted silver nitrate into silver metal last week and have already made jewelry out of some of it, of course I got a bit of it on my skin and have the brown spots but not too badly.😁
Believe me, scrub the stains with hydrogen peroxide. I found out by accident that this works amazingly well. Won’t get it off 100% but sure looks better than wearing those stains for a week and a half.
What causes that blue sparkle you showed at the end? Just beautiful! I think I'd spend more time staring at it than anything. 💜
Only ultra high purity silver does that. Not sure exactly what cause it.
This is actually really fascinating. Do you (or if any fans who see this and know if he does) have a list of all the various equipment and if needed brands to do the process from start to finish?
It’s all in the videos. Please watch and take notes
Where are you getting the silver nitrate? Assuming that bottle was 1/2 full ( 250 g) the current price of S-181Fisher Scientific silver nitrate is $9,000 USD per 500g so roughly $4,500 worth
Spot silver is currently $25.00 usd per OZ
25 x 9 oz = $225.00 ?
or am I missing something?
can you convert the pure silver bar into Silver Nitrate, now that seems like a money maker ! 😂
That bottle was very close to full, but I didn’t weigh it before I started, should have. It was donated by a chemist who shut down his lab. I gave the silver bar back to him the next day. I could easily dissolve some of my pure silver crystal in nitric, evaporate off the liquid in a desiccated, and make high purity silver nitrate. Or I could re-dissolve that bar and do the same. But I’ve already given it to the chemist.
I was wondering if this process could be used for sterling silver, like you did in your video, “Silver refining with household chemicals”. If so, and I used nitric to dissolve sterling, I could use HCl or sea salt for precipitation correct? Also, how would I neutralize the waste for disposal? I know I use angle iron for the copper nitrate but is that all that is needed? Or am I way off base completely lol. Love your videos man. Been on a binge for a hot minute 😊
Waste treatment.
do u have to add salt to the cottage cheese or is it good to eat right out of teh beaker?
At todays spot price for silver this final bar would be $228.78
As an avid stacker of silver bullion I ask …….. is this process, with all the costs of materials used, including the original silver nitrate, wouldn’t this process cost more than just purchasing silver bullion?
Probably. It took me three days, but I was dragging my feet.
@@sreetips why mine silver when you can make it like this?
@@patriotsouthern8123 Because that silver nitrate was made with mined silver. The silver has to come from somewhere and that always is mines (even if you have to trace it back a couple of millennia).
