Electrolysis of copper(II) sulfate solution with graphite electrodes

When a solution of copper(II) sulfate is electrolysed using graphite electrodes, copper metal is formed on the cathode by reduction of copper ions in the solution. At the anode, hydroxide ions are oxidised and form oxygen gas, which can be seen as bubbles, and water molecules

Quite safe

See my video 'nitrogen dioxide generated' You need concentrated nitric acid. Where are you. It is difficult to get I expect. The vapour is poisonous! Use excess copper to neutralise all the nitric. Leave it for a day or two. Then filter off excess copper one single big lump of iron. It will displace the copper. If you use lot of bits you wont be able to separate them from the copper.

Overall stoichiometry: 2CuSO4 + 2H20 =4e=> 2H2SO4 + O2 + 2Cu

@ChemPics right after 6 weeks of using this product bit.ly\uVlBLX Everyone can not believe how silky my legs are. They ask me if it's because I'm a blonde that there's hardly any hair ther, and I told all of them I'm not a natural blond so, there's lots of hair there you just don't see it anymore… It is gone.

@straighter100 LOL !!

The 1 guy who disliked this licked the copper sulphate thinking it was Kool-Aid =)

You can get copper powder from the reaction in this vid it's formed at the cathode as a powder

@Pennielove Dihydrogen sulfur quadoxygen, otherwise known as sulfuric acid. I have a mediocre understanding of the process, but I'm under the impression that unless you drink the copper sulfate, the entire process is safe.

You made h2so4. Search it. If your a real chemist you'll know what it is.

@XxVizzinixX you could make copper acetate, which is copper metal+vinegar+hydrogen peroxide, then after drying the crystals add sulfuric acid and more hydrogen peroxide
