the full step by step guide on how to construct a sulfuric acid cell. This method is way better than using car battery juice since its specifically designed to make H2SO4. The proceedure on making the new partial dechlorinated PVC membranes will be in a future vid as the proceedure is quite long but worthwhile as its cheap and can handle sulfuric acid and chloroalkali cells but probably not perchloric acid which I will still try using it to produce perchloric acid one of these days.
getting practical was a whole different world for me than programming was, its very makeshift, u need every cruddy idea you can come up with!!!
Finally got around to watching it, very cool.
You explain well man, nice vid
Awesome video! May I ask what material was the frame is made of?
foam board for illustrations :P
@MysteriusBhoice Thank you for the prompt response 😊
I would love to replicate this, but had a few other questions:
1) For the anode side, what ratio did you use for the Plaster of Paris and Sodium Hydroxide solution?
2) For the cathode side, does it matter how much Plaster of Paris I mix with the water?
3) What voltage/amperage did you use for the electrolysis?
4) You mentioned that you switched electrodes during the electrolysis. After completing your experiment, what type of electrode you suggest I use?
5) How many days did you end up running the electrolysis for before you achieved a desired outcome?
6) I didn't quite understand 13:30. Why did you pour the Sodium Sulfate solution back into the bottle?
Thanks again for all your help and guidance! 👍😊
@Nnamerz 1. anode side liquid is sodium sulfate or dillute sulfuric acid.
2. its a continuos process so the plaster gets used up but be sure to know that eventually the plaster forms a hard brick which gets destroyed into a fine slush of Ca(OH)2. Also NaOH is a catalyst but generally adding about 0.1 molar is good.
3. voltage depends on the membrane but generally 8-12 volts and the amps totally depend on the setup but mine ran at 10 amps.
4. switching was done because graphite is terrible and the good electrodes are lead sheets or the use of Ir-Ta doped TiO2 which is available on aliexpress or PbO2 coated mixed metal oxide electrodes.
5. you need to watch the current because it will drop and when it drops to a value where it no longer changes for half a day then it means the cell is at equilibrium.
6. the sodium sulfate had Ca(OH)2 in it which is bad to put into the anode chamber as it can cause membrane fouling due to the divalent ions attempting to cross over into the cathode chamber only to be trapped by the ion exchange groups which will block them.
Thats awesome! Great video
hi it's me again, can u replace naoh with milder base like sodium carbonate/bicarbonate?
Looks good. Figure out your yield yet?
gypsum be dirt cheap it dont matter much XD
but I do have about 300ml of H2SO4 from a few runs and ive improved the cell quite a bit with a bubbler agitator for cooling and the agitation keeps the gypsum in suspension and not settling down.
@MysteriusBhoice It matters when you want to concentrate it.Have you tritated it?
Did you made any HCl gas in your lifetime?
yes check other vid
@MysteriusBhoice it looks like you may have inhaled too much of it
Can I get this video without Confirmation of Age? - are you an Telegram, btw?
gypsum should have been solidified after a while
yes it would but then the reaction converts it into Ca(OH)2 which would then turn back into sludge.
@MysteriusBhoice you mean the electrolysis process takes place faster than the solidification of gypsum?
@Anar huseynov no but the solid gypsum reacts with the NaOH catalyst which is formed from electrolysis of Na2SO4 or added NaOH to form Ca(OH)2 and Na2SO4 again

Where'd you get the semi-permeable PVC membrane?
Also:
This is an absolutely AMAZING project!

new video on how to make it comming soon filming it now but the process of making it is quite long!!

@MysteriusBhoice I can imagine.
I'm just grateful you're taking the time to mak these projects & videos.
Have a great Sunday!
