Question

During the refining of an impure metal by electrolysis, the pure metal is a deposited:
(a) at cathode
(b) on the walls of electrolytic tank
(c) at anode
(d) at the bottom of electrolytic tank

Solution

(a) at cathode
In electrolytic refining, pure metal is always deposited at the cathode. The impure metal is made anode (positive terminal) and a thin rod of pure metal is made cathode (negative terminal). The salt of the metal  is made electrolyte in the cell. When electricity passed through the cell, the impure metal dissolves in the electrolytic solution. The pure metal from the electrolytic solutions moves and gets deposited at the cathode.

  Is there an error in this question or solution?
