Question

Write reactions at cathode and anode
when electrolysis of molten CuSO4
takes place with copper cathode and
platinum anode.
(Also write your observation at both
cathode and anode.)

Answer 1

Explanation:

The anode (positive electrode ) is made from impure copper and the cathode (negative electrode) is made from pure copper. During electrolysis, the anode loses mass as copper dissolves, and the cathode gains mass as copper is deposited. A half-equation shows what happens at one of the electrodes during electrolysis.
