Question

Write equations for the reactions taking place at the two electrodes (mentioning clearly the name of the electrode) during the electrolysis of Acidified copper sulphate solution with copper electrodes

Answer 1

Electrodes: Cathode: Copper

Anode: Platinum

Reaction at the cathode: `Cu^(2+) + 2e^(-) -> Cu`

Reaction at andde: `4OH^(-) - 4e^(-) -> 4OH`

                            `2OH + 2OH -> 2H_2O + O_2`
