- Please note that in the video I accidentally labeled anode and cathode opposite of what they should be. It should say copper cathode, lead anode. Ask any questions in the comments!

Wow! Very simple but in depth explanation! To the point, but easy to understand! Just what I needed! Subscribed my man
Except the result is a shitty PbO2 anode, lmao
A nice and simple way to make lead dioxide electrodes :) Good idea!
Sweet! I was looking for a simple method like this, thanks!
That is awesome. Keep up the good work!
Thanks, I will!
+Serpaz Tamor That is what I was worried about. I will be trying to plate the lead dioxide onto a more substantial substrate in the future.
Hello would Sodium bisulfate (NaHSO4) work as a replacement? Thanks.
I know commercially coated electrodes usually have uncoated part and your process of making this leaves uncoated part but surely the whole surface is conductive. I'm just wondering why you stress a need to sand the top for connecting to a power supply?
Please answer can i use lead oxide anode instead of lead dioxide for perchlorate electrolysis?
In this situation the anode is considered positive and the cathode negative.
Could I use hydrochloric acid instead?
Would you please simplified way to make lead borate?
can use this replace MMO anode？
What's name of intro music
For Chlorate-perchlorate electrolysis It must be done by electrodeposition of lead nitrate copper nitrate acetone or non Ionic surface agend surfactant process making anode for stand this corrosives environments of Chlorate-perchlorate cells at leas 3mm coating without bubble forming in surface using right temperature control 60C° ph control ( acidic conditions 3ph) current density low for beta or high for alpha type also in the process must used vibrator or ultrasonic cleaner or the Anode must move inside the solution to not form bubbles on the surface!!! As for the process is painful for someone that begin now as amateur chemist to produce this kind of anode !!!
Whether this anode will be suitable for perchlorate electrolysing?
How much amps did you use?
What was amperage?
Using epsom salt baking soda or even alum also works. though is not very quick. May take several hours.
Can HCl be used in solution instead as it also disassociates appreciably in to H3O+?
+cobrasniper555 no it cant be used as the anode will release cl 2 gas not oxygen and this will passivate your lead bar and prevent further current flow got it
thanks for the video, just wanna ask : how can the substrate affect the electrodeposition of lead dioxide?, i mean what's the difference -for example- between a platinum substrate and titanium one?
Thanks! From what I know it's more of a matter of durability. The lead dioxide will hold onto certain materials like titanium and carbon better than it would on just pure lead. This means they will last longer and will cause you less frustration in the long run. Time will tell how long the ones in the video will last.
+Gooferking Science got it, thanks a lot, keep up the good work..... ^_^
hello very nice video would the LD electrode that you made stand in a chlorate or a perchlorate cell
It should. I know this is two years late but they were originally used for that
I was wondering...since sulfurous acid (H2SO3) is quite easy to get here, but sulfuric acid isn't. Could I use that instead?
Hello 5 years late. I wonder if adding H2O2 to sulfurous acid would oxidize it to sulfuric, provided you don't add excess peroxide, that would make piranha solution.
@@Peaserist it would
I made it, looked just like yours, but as soon as I tried to run a chlorate cell with one the solution turned brown after an hour.
If I used a titanium or graphite substrate, would this still happen
That's normal, the browning is from chlorine gas generated during the process which is needed for the conversion of chloride to chlorate.
wrong
Wow so I'm assuming that's pretty inert! Is there anything it is incompatible with?
I'm not sure, but there are some drawbacks. The lead dioxide coating can be damaged. It would be more resistant to breaking if it were on a substrate such as carbon or titanium. I will cover this process in the future.
+Gooferking Science when exactly?
Is there a bismuth equivalent to this? To avoid the toxicity of lead?
Isnt bismuth way more prone to just breaking off instandly?
Super!
For a positive plate,,lead oxide or lead dioxide,, which one will give better amperage in a lead battery
Lead Oxide PbO2
@@kunaldhar6713 you are right
If the lead bar is hooked to the positive terminal , shouldn't it be the anode?
Yeah you're correct I made a mistake while editing the video and I meant to say it the other way around.
LOL I do stuff like that all the time. :P :)
Perhaps could use the positive plates of a dismantled lead acid battery
you can use negitive plates. positive plates or Pbo2 will NOT Work
I saw that you completed this process using 1.5 volts DC. How many amps were you running and what did you use as a power source?
Also, just a quick question about the finished product, how thick of a coating was formed onto the lead electrode..
Thanks, great video.
Hello Macka , my setup is old microwave oven transformer (MOT) with secondary wining removed and thick wire wind on the secondary on its place: the AC voltage from MOT need to be rectified to a DC voltage by a DIODE bridge. The AC voltage need to be divided by 1.414 constant to get your try DC voltage. So, you need around 2.2V AC and current to be from 5 to 20 Amperes. To match current will make lead oxide too brittle and it will be fulling of the lead electrode.
You have no control over the current unless some of these things get changed: higher voltage allows higher current to pass, or the size of electeodes is higher or the concentration of the solution is higher!
Heya, The best ideas that I have read was on Volt daddy (i found it on google) Probably the most detailed info on batteries and this kind of things that I have found.
can I use salt water for the electrolyte
Yes but at higher volts ,
hi , thanks for the video .
where did you get the lead from ?
I'm glad you enjoyed it! I don't honestly remember... but it is pretty easy to get a hold of.
:)
you said at the end of the video, it would be better to plate titanium with PbO2 , where is the video ? :)
+Ahmed Khodeir I plan on making a video in the future where I coat a different substrate in lead dioxide.
Buy some lead fishing weights (sinkers)
Is the sulfuric acid Reusable many Times?
Yes, As long as you wish. the water will decrease and the soloution's concertration will increase so you have to frequently top it up with distilled water.Let me know if my reply even helped a bit.
It is important to use copper for the - ?
nope
Can anyone tell me why my electrode just turns brown when being made and when used in sodium chloride it generates chlorine gas and falls apart turning the electrolyte brown
sodium chloride forms sodium chlorate, chlorine, and other weird chlorine compounds that are corroding your anode. Use potassium hydroxide as an electrolyte or just use 30% sulferic acid instead
So I won’t be able to make chlorates with the electrode?
So I won’t be able to make chlorates with the electrode?
@@jamesphillips8679 Most electrodes arent suited for making chlorates, only MMO, platinum work well. Graphite kind off does.
@@Linus-nq2op oh I had read somewhere that lead dioxide works too. Guess not.
That's sick
Thanks!
Are there any solvents that the lead dioxide is soluble in?
It is soluble in acetic acid.
thank you.
lead dioxide is soluble in ANY acid that forms water soluble lead salt providing you add hydrogen peroxide as a reducing agent. So the acids fluosilicic, fluoroboric, nitric, acetic, and perchloric would work once peroxide is added. Chloric acid may be reduced to chlorine dioxide by hydrogen peroxide.
+antiswattt3 If we are going to be anal about it, it reacts THEN dissolves. Lead dioxide is reduced in nitric acid solution by peroxide. Lead nitrate is formed then dissolves in aqueous acid solvent.
+antiswattt3 Yes your point is valid. However, we are not talking about elemental lead but lead dioxide. On a grand scheme, most lead salts are in fact insoluble. I merely wish to point out that there are a handful acids which form soluble salts with lead and once the proper redox reaction is performed, the lead is in effect solvated as the lead ion.
Could I use copper sulfate instead of sulfuric acid?
No
Is it good for perchlorate cell?
I think so
nah, will fall apart
can it be used for making chlorates?
Yes, and perchlorates!
Gooferking Science I have never dealt with electrochemistry or perchlorates, so what method do you use?
+Gooferking Science
In Chlorate Perchlorate cell you need thick minimum 3mm (Beta)
Lead Dioxide coating. Your lead dioxide method is (Alpha) PBO2 and not (Beta) PBO2. If it were that easy on sciencemadness or APC on forums it would have been a long time using.But it will not work in Chlorate Perchlorate cells with this method.If you want it to work with Chlorate,Perchlorate cells you need a strong minimum 3mm (Beta) lead dioxide TSLD Titanium substrate Lead Dioxide or GSLD Graphite substrate Lead Dioxide anode with the Lead Nitrate, copper Nitrate electrodeposition patented method, as it is done at the factory for this purpose .If it is not made from the patented processes as do the factories (for chlorate,perchlorate production) it will not work in chlorate,perchlorate cells.
Are you sure that copper is anode and lead is katod, may be conversely?
It would be, but this is a galvanic cell instead of an electrolytic cell. In that case anode and cathode are labeled opposite of usual.
Oh woops I got a little mixed up. I labeled them wrong I'm editing but color coded them right. Sorry about that!
How did you learn what you know?
Mainly the Internet, reading textbooks, and the science madness forum.
You're a genius, I'm jealous of your knowledge. Do me a favor please, I'm going to list several subjects, please rate 1 through 5 based on your understanding of them.
Programming
Engineering
Physics
Circuitry
Philosophy
this anode is good for producing H2SO4 from rock containing gypsum!!
Gypsum is insoluble in water
@@user-jp3of7hu9b it is slightly soluble
Is this lab in your home?
No, it is in a detached garage.
One complaint. "thoroughly wash your glassware" Where? I don't recommend introducing more lead into the environment.
Dilution is key to disposing of any hazmat.
There is already lead in the waterways from street runoff carrying particles from lead tire weights to either sewage plants (cities with combined systems) or storm runoff to local waterways (seperate street drain and sanitary sewage systems.)
Pick up tire weights when you see the in the street and dispose of them in a safe manner.
Don’t huff solder fumes or lick your fingers when playing with fishing weights.
I am making a video on making elemental chromium from ammonium dichromate, and burning this chemical is said to be dangerous. the products are nitrogen, steam, and chromium (III) Oxide. The oxide is the most dangerous if done outside. That is all, right? It shouldn't be very dangerous. Also, I have editing software now! I can make videos! I watch filmriot sometimes, and they showed hitfilm 3 off. It works great.
Camroc37 Chromium (III) Oxide is not that dangerous, as it is not soluble. I would be MUCH more worried about the ammonium dichromate itself.
Davy Zeng I am more worried about it for sure.
have you tested it out
Yes, and they work!
They did not for me...
why do I feel you mislabeled the anode and cathode
Ziggy Chomptwo I said that I did in the description
>
Does not work for making chlorates with this method.I tested and the lead dioxide coating damaged.This electrode made by electroplating with PBNO3 for chlorates,perchlorates and not the H2SO4 method.The process is good,but not for making a anode for chlorates or perchlorates.
At 30% NaHSO4 or KHSO4.
it just corrode within a use of 5min
did you try it in chlorate cell?
wrong method
What the f havent u ever gone fishing dude just dont eat the lead its not that bad
lol this kid scared of touching lead
There is no safe level of lead known, lead is accumulative, and is a known carcinogen and neurotoxic, and the cognitive deficits induced is permanant!
@@digifomation yes, and I’m afraid lead metal, lead oxide nor its carbonate can absorb through your skin
@@digifomation on top of that, chelating agents can be used to remove lead from the body if he did manage to ingest soluble lead, witch he isn’t even doing. Touching lead is nothing to be afraid of, it cannot absorb through your skin in its metallic or oxide forms becouse that necessitates it being soluble in water
@@digifomation and as a final statement, although lead poisoning in cumulative when ingested chronically, lead is still excreted through the urine and is only cumulative when allowed to build up enough of start being incorporated into neural, bone tissue ext.. the fear of touching lead is one based in fear not facts
