Electrolysis Of Copper

THE ELECTROLYSIS OF SOLUTIONS - chemguide

The electrolysis of copper(II) sulphate solution using a copper anode. A similar change happens if you electrolyse copper(II) sulphate solution using copper electrodes. Copper is deposited at the cathode as you would expect, but instead of oxygen being given off at the anode, copper(II) ions go into solution. Again, there is a net transfer of ...
