Whenever I'm making any crystals like this whether it's potassium chlorate or ammonium nitrate I like to put my final solution into a pan with alot if surface area to give the crystals more room to grow but this was a great video
It does! To me it tastes more salty than regular salt. I only bought it for science use though :) Potassium chlorate is much less soluble than sodium chlorate, so you're able to separate it from the NaCl easily.
From 2024. Remember: chlorine gas reacts with an aqueous solution of sodium hydroxide and the first products are sodium hypochlorite and sodium chloride, while temperature raises. So heating a solution of sodium hypochlorite allows the inverse reaction: NaCl + NaClO -> NaOH + Cl2 (1). Even if you have a pure NaClO solution the following equilibrium exists: NaClO + H2O NaOH + HClO (2) and very unstable acid 2HClO 2HCl + O2 (3) and HCl + NaOH NaCl + H2O (4). So every conditions for (1) are present. Perhaps it's more effective dropping a concentrated sodium hydroxide solution.
It has an important use as a chemical oxygen generator, used in space stations, aircraft, and submarines. It decomposes into oxygen and KCl on fairly gentle heating, so it's an easy source of the gas. It's also much more compact than storing pressurized O2 tanks. It's also, of course, a powerful oxidizer, and can be used in other chemistry that requires such things.
Thanks! A lot of my equipment is from eBay or various other online sellers, as well as buying from other chemistry hobbyists. A fume hood is definitely preferable, and necessary for some experiments - until I get one I do many of my reactions outside, preferably when it's windy.
Where would the nitrate come from though? All I used was bleach and potassium chloride. It's possible there was some contamination, but I don't think there'd be enough of it for as many needle crystals as I saw.
It depends on the experiment, but on average I'd say it's at least a full day of doing the experiment (mixing things, waiting to filter or boil, etc.) and then a few hours editing the video clips together. Even simple things tend to take quite a while to set up, perform, and break down. Good catch on the spill, whoops :P
You can get 40lbs of pure KCL at ACE or LOWES for around $25. Great video, I can't wait to see you try electrolysis, it's so fun and exciting when you see those crystals fall out, great feeling.
It's just boiling bleach and then adding No-Salt! :) But I understand if stuff like this makes people uncomfortable. Boiling bleach isn't a fun thing to be around, for sure. If you aren't comfortable working with this stuff, then you should definitely buy it instead. eBay is your friend!
Really, I was just trying to make a funny. I respect chemicals but I would attempt this in the back yard out by my shed. For sure I would stay upwind from it. I think I have always had something against bleach every since my mother made me clean with it when I was young. I have used swimming pool bleach in my pool which is marked 10% bleach. Have a good day.
mrhomescientist I used 50% bleach a while back, (about 6$) for making chlorobutanol. When a bit heated it stings& burns my hands a few times.! btw, Love your vids mate, nice experiments and a dream for an amateur chemist.!
Did you end up attempting any recrystallization, and if so did you get any additional product? I mean sure, given the chemicals were just household bleach and salt substitute, but I hate to see waste on a certain level. Anyway, love the videos, looking forward to the electrolysis version.
I boiled down bleach until I saw salt like crystals moving around in the solution then took it off the heat. Cooled it down in the fridge, mixed the cold saturated potassium chloride solution with the sodium chlorate solution and NO crystals of any sort were created. Where did I go wrong??
Greeting! Good video! I found bleach with 26.7% sodium hypochlorite! It also contains 0.09% sodium tosylchloramide! Can I use this to make potassium chlorate?
Second batch looks like it has a ton of potassium chloride in it. Next time try a saturated solution not a supper saturated solution. Maybe you will recover more chlorate than chloride that way. I also purify my potassium chloride salt first before making a solution. The salt has anti caking agent and preservatives. Fortunately they are all not very soluble in water so you can easily remove them. Or buy some potassium chloride salt for a water softener its was less per ounce or lbs and higher purity
Whenever I'm making any crystals like this whether it's potassium chlorate or ammonium nitrate I like to put my final solution into a pan with alot if surface area to give the crystals more room to grow but this was a great video
If you dont mind, i have some non requested sugestions: - When you see NaCl cristals forming in the bleach, add more water, so you'll need to heat it more and increase the NaClO3 forming and also decreasing the contamination of your final product by hypoclorite (dangerous if you are using it for explosives). - When mixing the two saturated solutions you can also boil it until cristals start to form, then you can leave it to cool in the freezer and therefore squeeze more product.
There is always a major side effect from doing pyrotechnics. It's called perma grinning, laughing and it is simply unavoidable, even those who do this for a living, still have a big smile on their faces when they set off a detonation or a chemical reaction that causes a major pyrotechnical result. Take care my Friend, always a joy to learn, and have the type of fun that to be honest is "good clean fun" if we are using our heads.😂
Thanks a lot! I'm not a teacher, though I do co-host a science stage show for elementary kids through my work. Almost all of my chemistry knowledge is self-taught. Just sitting down and reading a lot about the subject, then going out and trying things myself!
OMG! First I saw your melting aluminium video and when I watched this I recognised the voice and found out it was you again! DUDE YOU ARE ON MY AWESOMENESS RADAR!!!
The only side effect of pyrotechnical reactions is Perma grinning, and laughter, I think it has much to do with the child in all of us, and also the fact that you just can't detonate something(in a controlled environment) without giggles and smiles, the bigger the reaction, the bigger the smiles and giggles. This is even the case with those who do this all the time, old lab guys simply can't make a good pyrotechnical reaction without letting out a giggle and a huge smile on our faces. Take care Friend, always nice to see someone notice the same thing as I have.😀
A car battery's acid is only about 30%, nowhere near the point where you can call it concentrated. You could of course boil the water off, but that takes a while and boiling acid isn't very friendly. Mine was liquid drain opener, and is 98% acid.
Another question... Is the precipitate (from the initial boiled bleach) completely sodium chloride, with no sodium chlorate in the precipitate? Could you increase the yield of crystals by, perhaps adding some water, re-dissolve the salts into the solution and THEN add the potassium chloride solution?
There's probably at least some chlorate in it, but the vast majority should be chloride. The chlorate is much more soluble and should remain in solution. Your idea would probably work, but I don't think the increase in yield would be very significant. Remember also that adding more water will dissolve more of your desired product!
I just finished making some potassium chloride and sodium chlorite mixture and it's currently in the fridge. Not 100% sure it will turn out well, but there seem to be some solids collecting on the bottom, so that's good. I can confirm that it has to be regular bleach without any scent, since the bubbles and other impurities prevent the NaCl crystals from forming during boiling. There are definitely fumes that come off, and if you don't have a fume hood, you should definitely do this outside. I was able to get sodium chlorite from my bleach by using a ceramic type glass in a campfire, and even though it had a small amount of ash that floated in, using a coffee filter made it appear as clear as it does in the video. I also didn't have any precipitate upon the initial mixing, so don't be too discouraged if you do this experiment and don't get an instant return. Hope this helps!
well i made some last night i boild down 3000ml to 900ml let it cool to room temp filter 3 times through double filter then u want 30 grams of potassium per 200ml so 600ml 90 grams no salt filter through double filter 3 times after letting cool to room temp in separate container then filter through a single filter together in same container let sit in freezer over night i got 42 grams of plate glass crystals i mixed with half mass sugar and i make flash powder from perchlorate and aluminum powder and let me say that the potassium chlorate and sugar i made was way faster and hotter the the flash its really powerful stuff so be careful 9 grams in a half inch pvc piece of pipe 3 inches long and end caps pack semi tight and u got i would say about half a stick of tnt 30 gram is about a full stick so be careful i say again and enjoy my fellow pyros ;)-
hello! I was just wondering if you have tried using Pool Brite Sanitizer Liquid Disinfectant? it has the same properties as bleach except it is 12.5% Sodium Hyperchlorite. I was able to yield twice as much and a higher chance of high purity Chlorate from the pool brite than the 8.25% bleach. You should give it a try if you get a chance!
Hm, I come up with 41.25g hypochlorite to start, then 19.65g sodium chlorate after disproportionation, and a theoretical yield of 22.6g potassium chlorate at the end. Then 9g is about a 40% yield. Check the link in the description for my blog post with some more details. I'm not sure where our math differs. I used 8.25 wt.% of bleach to start. In either case it's not an abysmal yield, but the electrolysis method is much better from what I hear. I'll need to try it out.
Wow😱, I'm amazed This reaction was my first test in General Chemistry 1 earlier this year(due to the pandemic I never got the chance to practically understand it). Thank you Sir. The feeling of satisfaction I get when I finally understand something reminds me why I love chemistry.
Do you think if you let the solution cool down very slowly in the recrystallization process that you might get more yield..? I herd somewhere that the slower a solution cools down the more crystals form... Don't know if it's true.. Any thoughts...?
Great video! I just wanted to mention you MUST use glass to boil the bleach. If you use metal you will get side reactions that will ruin your synthesis and you won't get any product. I am sure there is some type of metal that you can use, but I tried a few and they didn't work. Does anyone know what type metal will not ruin the experiment? I want to go large and metal is more practical.
Maybe my calculations are off, but 9g seems like a reasonable yield considering the process. There were over 40g of hypochlorite, but that leaves only 13g of chlorate after heating, for a nominal yield of 15g of KClO3. 56% yield is better than a poke in the eye.
I think pool supply stores sell concentrated sodium hypochlorite as liquid pool shocker. It is usually sold in gallon size tan jugs. Though I could be wrong and it's an entirely different compound.
Mix those crystals (the purer ones) with equal weight amount of 90% melted beeswax/10% vaseline, cool in blocks and add a blast cap and you've got yourself homemade plastic explosive. Just saying...
Or one could add the right fuel to it and you have a high explosive, Ive always used a large floating steel bowl in a dry ice bath that you would drip into, There are also easier and faster ways to scrounge up chlorate without any chemistry, you just know where to look
It's chloride - NaCl. Sodium chlorate is very soluble and remains in solution, which is why we add KCl to the solution to get out the much less soluble potassium chlorate. It's possible that if the bleach is boiled down too much you could get some sodium chlorate precipitation, which is why you want to remove it from heat as soon as crystals start appearing.
KClo3 has the lowest solubility in 0°C water, that makes washing you salt+Chlorate easy. Rebatch you wash water so not to waste any small quantity of KClO3
60 grams potassium chlorate + 125 grams copper sulphate + 1 liter of hot water. Filter then immerse zinc and pot metal to dye black when exposed to air. Rinse and dry or repeat as needed. I don't need you getting the wrong Idea FBI.I know you're stealing my fertilizer shipments. That's not even the right kind you dingus. I blame you for ruining my melon season.
Formation of chlorate is favorable at low ph. Bleach typically has a ph of 11 or so. Decrease ph with HCL to about 6.5. This increases efficiency and has the added benefit of decreasing chlorine off gassing during the boiling process. Ph may raise while boiling. Adjust as necessary.
No, this would not work. You have to prepare an ammoniacal solution of copper(I) ion, and pass the acetylene through that. I've done this many times, could possibly upload a video on it if you want.
Yeah the impurities are sodium chloride or potassium chloride since you converted it but You're never going to get anywhere near the theoretical yield doing this process The only real way to do this efficiently is through electrochemical reaction and even then you're going to have to do many steps to achieve a really efficient cell like balancing pH non-stop I once built an automatic pH adjustment system which was a big pain in the ass it wasn't worth it but it was nice once it was done
perhaps you can use swimming pool chlorinator, it comes as a powder. Not sure if it’s pure NaClO3. Also bleach comes with a small amount of sodium hydroxide, presumably to offset the chlorine in the water turning into hydrochloric acid. Probably irrelevant with all that sodium chloride present.
I never considered an acid to start the flame - I use the chlorate for making colored smoke bombs, and the idea of having a small ampule inside that breaks and starts the reaction when you "throw" the grenade seems appealing (although, not safe at all - the pull tabs I use now are much safer).
I have some chemistry from college days ( a year,so no chemist but no dummy either) and after three true at this relatively simple reaction,using proper equipment I was unable to produce pyrotechnic grade chlorate I could use. It would burn but mixed with sulphur and banged with a hammer it should have been able to generate a return bang but did not and with aluminum couldn't become flashpowder either. It was a.waste.of time. Better luck to the rest.of.u.
i have perfected this method if u get 8.25% sodium hypochloride bleach boil 1000ml down to 300 filter it will leave u with 200 cuz all the sodium will crystalize let it cool for 2 hours before u filter so all the sodium will fall out make sure its room temp then filter now take 200ml of no salt or potassium boil to make sure it is all dissolved let it cool for 2 hours stir vigorlessly then filter in separate container then filter the bleach solution again oh make sure u have 2 to 3 layers of coffee filter i use 3 after u filter both twice each time with clean filters very important then use 3 layers dress filters then filter both solutions into the same container then put in freezer over night take out the container it will be all glass crystal oh sry u use 30 grams of potassium in the solution filter out all water the lay all crystals on a thick news paper and spred even across the paper and lay another thick paper on top with some weight let dry for 3 hours then transfer to another stack of paper repeat several times till bone dry it usealy takes 24 hours u will yield about 20 to 35 grams of some powerful shit no joke be careful i mixed 12 grams of potassium chlorate and 6 grams of sugar and 1 gram aluminum powder not nessasary but it gives it a little more bang and makes to flash nice but this mix in 3/4 inch pvc pipe and make sure to pack tire not super but tight i also had some 4f black powder and made a pvc bomb with 100 grams and it was like a wisper compare to the chlorate mix no joke and it blew a hole in the ground 5 inches deep and 11 inches wide and i did not put in the ground just layer it on top and the 4f black powder left 3 inches deep and 6 wide it dose take some time to make such a small amount but it takes 5 days for electrolysis i can make double in five days its all how u concentrate it mine dose not even smell like bleach one bit so there u go a much better way to get potassium chlorate i thank the man who made this video cuz without it i could not have learned this method and his way was not powerful at all it could only be used to make rockets r-candy fuel and forget the match head way i melted 900 matches and got 2 grams of perchlorate for perchlorate use electrolysis anyway enjoy u will love it I'm sure!!!!!!
I don't know much about chemistry, I did horribly with it in HS, so please bear this in mind when I ask: Is there a way you can "seed" the crystal formulation somehow to increase yield?
Sure, if you have some solid potassium chlorate already you can throw it in to kickstart crystal formation. But it won't increase yield any. It just makes it a bit easier to grow them.
just take your second crystal lot, dissolve in the minimum amount of fairly hoy water to just disolve it all,then allow to cool slowly to room temp, decant,get crystals,then put left over liquid in the fridge to get last bit out...well, thats the usual method to attempt full recovery....also,during your first step, try to prolong that boiling,adding water to replace any lost.
Here, low sodium salt are actually a 50/50 mix of sodium or potasium salt... with this: If I add first this salt mix to the bleach and then boile it later: Does it will improve the potassium chlorate yield?...thinking about the extra sodium salt added could balance the reaction into producing chlorates since there already too much chloride ions inside.. is this right?... or it doesn't works this way?
My low salt has shed loads of sodium chloride in it.... Per 100g 33g of salt and 34600mg of potassium lol so this shit is over 30 percent magnesium carbonate and sodium hexacyanoferrate..... Nice, right???
I usually leave these things overnight, so they have time to precipitate everything. Don't worry about the whole thing freezing - having so much stuff dissolved in it has lowered the melting point of the water so your fridge shouldn't freeze it solid. As I say in the video, evaporation won't work because the reaction happens with boiling temperature only. Make sure you boiled it vigorously until you just start to see crystals appear, then refrigerate overnight.
At what temperature did you boil the bleach? What was the temperature of the bleach solution when you took it off the heat? How long did you have it on the heat for? FYI. I used Jik 3,5% m/v Sodium Hypochlorite solution.
I didn't measure the temperature, but surely it was near 100 C. I simply held it at that point until crystals started forming, I don't recall how long that was. It sounds like you did everything right, but your bleach solution is pretty dilute. How much did you start with? 500mL of my 8.25% solution produced very little yield, so you'd probably need over a liter to get anything worthwhile from yours.
You want an ion exchange.. putting sodium chlorate into the solution after disporprotionating the NaClO would be pointless.. lmao! And KCl is used to lower one's sodium intake by replacing it by potassium
The potassium is just the counterion. Sodium chlorate works just as well as potassium chlorate. The part that you care about is the chlorate, so you're doing a lot of work for no reason.
U Uthgaard Except that sodium chlorate is much, much more soluble than potassium chlorate, so it's a lot harder to get it out of solution and as pure as the potassium method.
What would happen if 66 cows were to ingest this?
D E A T H
I love that chuckle at the end of the reaction lol
I swear to god its like the tell tale sign of a manic pyro.

Where would the nitrate come from though? All I used was bleach and potassium chloride. It's possible there was some contamination, but I don't think there'd be enough of it for as many needle crystals as I saw.

In either case it's not an abysmal yield, but the electrolysis method is much better from what I hear. I'll need to try it out.
Men my blech have, 50 gr of chlorine of 1 liter. It is work?
50 grains? are you sure that's even bleach?
@@pacman10182 grams not grains
@@spoonerman gr is grains, g is grams
@@pacman10182 People type gr for grams despite not being correct. Also the guy is from Europe i doubt he uses grains.
@@spoonerman even more reason for me to make fun of him
Wow😱, I'm amazed
This reaction was my first test in General Chemistry 1 earlier this year(due to the pandemic I never got the chance to practically understand it). Thank you Sir. The feeling of satisfaction I get when I finally understand something reminds me why I love chemistry.
Do you think if you let the solution cool down very slowly in the recrystallization process that you might get more yield..? I herd somewhere that the slower a solution cools down the more crystals form... Don't know if it's true.. Any thoughts...?
Can I disolve Calcium Hypochlorite (pool chlorine) on water and do the same procedure? Would it work? Since both are hipochlorites?
Great video! I just wanted to mention you MUST use glass to boil the bleach. If you use metal you will get side reactions that will ruin your synthesis and you won't get any product. I am sure there is some type of metal that you can use, but I tried a few and they didn't work. Does anyone know what type metal will not ruin the experiment? I want to go large and metal is more practical.
maybe teflon?????? don't take my word for it tho
Maybe my calculations are off, but 9g seems like a reasonable yield considering the process. There were over 40g of hypochlorite, but that leaves only 13g of chlorate after heating, for a nominal yield of 15g of KClO3. 56% yield is better than a poke in the eye.
I boiled bleach but there are no crystals forming Idk why
I think pool supply stores sell concentrated sodium hypochlorite as liquid pool shocker. It is usually sold in gallon size tan jugs. Though I could be wrong and it's an entirely different compound.
They do! Just be sure to read the labels carefully; there's a huge variety of pool chemicals so make sure you know what you're getting.
Mix those crystals (the purer ones) with equal weight amount of 90% melted beeswax/10% vaseline, cool in blocks and add a blast cap and you've got yourself homemade plastic explosive. Just saying...
Or one could add the right fuel to it and you have a high explosive, Ive always used a large floating steel bowl in a dry ice bath that you would drip into, There are also easier and faster ways to scrounge up chlorate without any chemistry, you just know where to look
🤫
it works with perchlorate
Maybe it’s just me, but I think your accent is like styropyro’s! And he also likes chemistry (in fact, he has a degree)... mmmh... suspicious.
It's chloride - NaCl. Sodium chlorate is very soluble and remains in solution, which is why we add KCl to the solution to get out the much less soluble potassium chlorate. It's possible that if the bleach is boiled down too much you could get some sodium chlorate precipitation, which is why you want to remove it from heat as soon as crystals start appearing.
KClo3 has the lowest solubility in 0°C water, that makes washing you salt+Chlorate easy. Rebatch you wash water so not to waste any small quantity of KClO3
One day i swear this guy is gonna make meth...
Thanks! Found liquid fire at ace hardware. Pretty pure stuff, though it does have quite a bit of carbon/organic impurities. :(
60 grams potassium chlorate + 125 grams copper sulphate + 1 liter of hot water. Filter then immerse zinc and pot metal to dye black when exposed to air. Rinse and dry or repeat as needed. I don't need you getting the wrong Idea FBI.I know you're stealing my fertilizer shipments. That's not even the right kind you dingus. I blame you for ruining my melon season.
@4:40 That laugh :D
Formation of chlorate is favorable at low ph. Bleach typically has a ph of 11 or so. Decrease ph with HCL to about 6.5. This increases efficiency and has the added benefit of decreasing chlorine off gassing during the boiling process. Ph may raise while boiling. Adjust as necessary.
Chlorine would sure offgas before the boil! But that's an interesting idea to try, thanks for the comment.
mrhomescientist for sure. Gradual/dilute is a good idea. Thanks for the video! This chemistry is always so entertaining.
No, this would not work. You have to prepare an ammoniacal solution of copper(I) ion, and pass the acetylene through that. I've done this many times, could possibly upload a video on it if you want.
Please
Yeah the impurities are sodium chloride or potassium chloride since you converted it but You're never going to get anywhere near the theoretical yield doing this process The only real way to do this efficiently is through electrochemical reaction and even then you're going to have to do many steps to achieve a really efficient cell like balancing pH non-stop I once built an automatic pH adjustment system which was a big pain in the ass it wasn't worth it but it was nice once it was done
perhaps you can use swimming pool chlorinator, it comes as a powder. Not sure if it’s pure NaClO3.
Also bleach comes with a small amount of sodium hydroxide, presumably to offset the chlorine in the water turning into hydrochloric acid. Probably irrelevant with all that sodium chloride present.
I never considered an acid to start the flame - I use the chlorate for making colored smoke bombs, and the idea of having a small ampule inside that breaks and starts the reaction when you "throw" the grenade seems appealing (although, not safe at all - the pull tabs I use now are much safer).
He reminds me of Walter white😂
can i use potassium nitrate instead of potassium chloride. i think that would work but i need someone to approve
Use for what?
@@fudes587 for the double displacement reaction
I have some chemistry from college days ( a year,so no chemist but no dummy either) and after three true at this relatively simple reaction,using proper equipment I was unable to produce pyrotechnic grade chlorate I could use. It would burn but mixed with sulphur and banged with a hammer it should have been able to generate a return bang but did not and with aluminum couldn't become flashpowder either. It was a.waste.of time. Better luck to the rest.of.u.
i have perfected this method if u get 8.25% sodium hypochloride bleach boil
1000ml down to 300 filter it will leave u with 200 cuz all the sodium will crystalize let it cool for 2 hours before u filter so all the sodium will fall out make sure its room temp then filter now take 200ml of no salt or potassium boil to make sure it is all dissolved let it cool for 2 hours stir vigorlessly then filter in separate container then filter the bleach solution again oh make sure u have 2 to 3 layers of coffee filter i use 3 after u filter both twice each time with clean filters very important then use 3 layers dress filters then filter both solutions into the same container then put in freezer over night take out the container it will be all glass crystal oh sry u use 30 grams of potassium in the solution filter out all water the lay all crystals on a thick news paper and spred even across the paper and lay another thick paper on top with some weight let dry for 3 hours then transfer to another stack of paper repeat several times till bone dry it usealy takes 24 hours u will yield about 20 to 35 grams of some powerful shit no joke be careful i mixed 12 grams of potassium chlorate and 6 grams of sugar and 1 gram aluminum powder not nessasary but it gives it a little more bang and makes to flash nice but this mix in 3/4 inch pvc pipe and make sure to pack tire not super but tight i also had some 4f black powder and made a pvc bomb with 100 grams and it was like a wisper compare to the chlorate mix no joke and it blew a hole in the ground 5 inches deep and 11 inches wide and i did not put in the ground just layer it on top and the 4f black powder left 3 inches deep and 6 wide it dose take some time to make such a small amount but it takes 5 days for electrolysis i can make double in five days its all how u concentrate it mine dose not even smell like bleach one bit so there u go a much better way to get potassium chlorate i thank the man who made this video cuz without it i could not have learned this method and his way was not powerful at all it could only be used to make rockets r-candy fuel and forget the match head way i melted 900 matches and got 2 grams of perchlorate for perchlorate use electrolysis anyway enjoy u will love it I'm sure!!!!!!
I like those videos, even though I don't have anything to do with chemistry.
Your voice is so friendly :D
And chemistry is awesome.
Hi, Have a good Day, Please you can explain how to make sodium chlorite = NaClO2? 🤔
I don't know much about chemistry, I did horribly with it in HS, so please bear this in mind when I ask: Is there a way you can "seed" the crystal formulation somehow to increase yield?
Sure, if you have some solid potassium chlorate already you can throw it in to kickstart crystal formation. But it won't increase yield any. It just makes it a bit easier to grow them.
I actually did this on a "little bit" larger scale. I boiled down 10 liters of 4% bleach. Xd
just take your second crystal lot, dissolve in the minimum amount of fairly hoy water to just disolve it all,then allow to cool slowly to room temp, decant,get crystals,then put left over liquid in the fridge to get last bit out...well, thats the usual method to attempt full recovery....also,during your first step, try to prolong that boiling,adding water to replace any lost.
One wayward pinch of potassium chloride one Erin twitch and KABLEWY
Thank you for balancing that for us.
Did anyone else notice the Ruger gloves? My man!
Is the crystal left after boiling the bleach pure sodium chloride?
Just kinda curious say what if ya boost your chloride say add some salt can street salt work or does it have to be no salt
Best source of KCL is water softener. Ya can get a 40lb bag for 25 bucks. I did electrolysis of Nosalt and there is quite a bit of mineral oil in it.
Is it better for a bleaching has a bigger or smaller% sodium hypochloride?
yeah that no salt stuff has quite a bit of sillicon dioxide (which obviously is insoluble)
Almost nine years later:
Most people use boiling chips as a nidus, not a stir bar. lol
Always remember to label your bleach when placing it the refrigerator! ha ha
Thanks Dan, new subscriber to your channel !
Here, low sodium salt are actually a 50/50 mix of sodium or potasium salt... with this: If I add first this salt mix to the bleach and then boile it later: Does it will improve the potassium chlorate yield?...thinking about the extra sodium salt added could balance the reaction into producing chlorates since there already too much chloride ions inside.. is this right?... or it doesn't works this way?
I am doing this right now. Protip: Do not use a stainless steel pot. You will ruin your yield, your pot and your mom becomes very angry.
My low salt has shed loads of sodium chloride in it.... Per 100g 33g of salt and 34600mg of potassium lol so this shit is over 30 percent magnesium carbonate and sodium hexacyanoferrate..... Nice, right???
Could you do a video extracting the Potassium Chlorate through electrolysis? I'd love to understand the science behind it.
How long should I leave it in the fridge? .... I did everything but not crystallized the potassium chlorate :(
I usually leave these things overnight, so they have time to precipitate everything. Don't worry about the whole thing freezing - having so much stuff dissolved in it has lowered the melting point of the water so your fridge shouldn't freeze it solid. As I say in the video, evaporation won't work because the reaction happens with boiling temperature only. Make sure you boiled it vigorously until you just start to see crystals appear, then refrigerate overnight.
At what temperature did you boil the bleach? What was the temperature of the bleach solution when you took it off the heat? How long did you have it on the heat for? FYI. I used Jik 3,5% m/v Sodium Hypochlorite solution.
I didn't measure the temperature, but surely it was near 100 C. I simply held it at that point until crystals started forming, I don't recall how long that was. It sounds like you did everything right, but your bleach solution is pretty dilute. How much did you start with? 500mL of my 8.25% solution produced very little yield, so you'd probably need over a liter to get anything worthwhile from yours.
Thanks. I got very little but it worked.
700ml
You want an ion exchange.. putting sodium chlorate into the solution after disporprotionating the NaClO would be pointless.. lmao!
And KCl is used to lower one's sodium intake by replacing it by potassium
The potassium is just the counterion. Sodium chlorate works just as well as potassium chlorate. The part that you care about is the chlorate, so you're doing a lot of work for no reason.
U Uthgaard Except that sodium chlorate is much, much more soluble than potassium chlorate, so it's a lot harder to get it out of solution and as pure as the potassium method.
What happens if you heat potassium chlorate in a microwave?
