Electric current is passed through two cells A and B series. Cell A contains aq. AgNO_3 and platinum electrodes while cell B contains aq. CuSO_4 and copper electrodes.

MHT CET Chemistry question

Electric current is passed through two cells A and B series. Cell A contains aq. and platinum electrodes while cell B contains aq. and copper electrodes.

(A)The cathode and anode reactions occurring in the two cells are different.Correct
(B)The cathode reaction in the two cells are identical but the anode reaction are different.
(C)The cathode reaction in the two cells are different but the anode reactions are identical
(D)Electrolysis occurs only in cell A and not in cell B.

Answer: (A)

Solution

In cell A, is reduced at the cathode and water is oxidised to at the platinum anode; in cell B, is reduced at
