Question

During extraction of metals, electolytic refining is used to obtain pure metals.
(a) Which material will be used as anode and cathode for refining of silver metal by this process?
(b) Suggest a suitable electrolyte also.
(c) In this electrolytic cell, where do we get pure silver after passing electric current?

Answer 1

1. During extraction of silver metal, impure metal will be used as anode and pure metal is used as a cathode for refining of silver metal by this electrolytic refining.
2. Silver Sulphate or Silver Nitrate could be used as an electrolyte.
3. Pure silver is obtained on the cathode.
