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
Solution
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`
