question_answer 57)

  What will happen during the electrolysis of aqueous solution ofCuS04 in the presence of Cu electrodes? (a) Copper will deposit at cathode     (b) Copper will dissolve at anode (c) Oxygen will be released at anode   (d) Copper will deposit at anode

Answer:

                  (a, b) Electrolysis of CuSO4 can be represented by two half cell reactions these occurring at cathode and anode respectively as At cathode                 At anode                     Here, Cu will deposit at cathode while copper will dissolved at anode. Hence, options (a) and (b) are the correct choices.
