In the electrolytic refining of zinc.........

A

graphite is at the anode

B

the impure metal is at the cathode

C

the metal ion gets reduced at the anode

D

acidified zinc sulphate is the electrolyte

Text Solution

Verified by Experts

The correct Answer is:
D
The impure zinc is purified electrolytically The impure metal is made anode and cathode consists of sheet of pure aluminium. A solution of zinc sulphate acts as an electrolyte. Zinc dissolves from anode and deposite on cathode when wlwctric current is passed.
