In the electrolytic refining of zinc,
1 graphite is at the anode
2 the impure metal is at the cathode
3 the metal ion gets reduced at the anode
4 acidified zinc sulphate is the electrolyte
Explanation:
The impure zinc is purified electrolytically. The impure metal is made anode and cathode consists of sheets of pure aluminium. A solution of zinc sulphate acts as an electrolyte. Zinc dissolves from anode and deposits on cathode when electric current is passed.
