(a) During extraction of metals, impure silver metal is used as the anode, and pure silver metal is used as the cathode for refining silver metal by this electrolytic refining.

(b) Electrolyte: Silver Sulphate or Silver Nitrate solution.

(c) In this electrolytic cell, Pure silver is obtained at the cathode as metals are electropositive in nature.
