Question

During electrolysis of copper sulphate, if electric current is passed through the electrolytic cell for a long time, what change would be seen at the anode?

Answer 1

• When electricity is passed for a long time through copper sulphate solution, the following reaction is seen at the anode: Anode Reaction: Cu(s) → Cu²⁺ (aq) + 2e^-
• All the copper atoms will get converted into copper ions and get deposited on the cathode. This process continues till the copper anode exists.
