During extraction of metals, electrolytic 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?
Ans. During electrolytic refining, impure metal is used as anode and pure metal is used as cathode. So, impure silver will be used as anode and pure silver will be used as cathode.
(b) Suggest a suitable electrolyte also.
Ans. Silver sulphate solution can be a suitable electrolyte.
(c) In this electrolytic cell, where do we get pure silver after passing electric current?
Ans. Pure silver will be obtained on cathode; because metals are electropositive.
