During electrolysis of aqueous cuso4
WebMar 25, 2024 · In the electrolysis of CuCl2 solution using Cu electrodes, the weight of Cu anode increased by 2 gram at cathode. In the anode. asked Mar 25, 2024 in Chemistry by Jahanwi ( 73.6k points) 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).
