Question

The electrolysis of aqueous solution of cubr2 using pt electrodes would lead to evolving of

Answer 1

Cu deposits at anode and liberation of bromine gas at cathode.

Answer 2

"Copper (Cu) at the cathode" is the answer.

Detailed explanation:

Below is the chemical reaction behind the electrolysis of aqueous solution of CuBr2 ( Copper Bromide) with use of Platinum electrodes (inert).

CuBr2   --------->    Cu$^{2+}$  +  2Br-

Reaction that happens at Anode:

2Br-     ------------>  Br2  +   2e-

Reaction that happens at Cathode:

Cu$^{2+}$  + 2e-    --------------->  Cu
