The anode (positive electrode ) is made from impure copper and the cathode … WebSolution. In this process of electrolysis, CuSO4 solution is electrolysed in the presence of Cu electrodes. Thus, at cathode, Cu2+ will get reduced to Cu and at anode Cu will get oxidised to Cu2+. Therefore, Copper will get deposited at cathode and copper will get dissolved at anode. Hence, the correct options are (a) and (b).
