Question

during extraction of metals , electrolytic refining is uaed to obtain pure metal

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 electolytic cell, where do we get pure silver after passing electric current .

​

Answer 1

Explanation:

(i) Anode: Impure silver metal

Cathode: Pure silver metal

(ii) Aqueous solution of a silver salt like AgNO3 can be used as an electrolyte.

(iii) We get pure silver at cathode, because at cathode, reduction reaction will takes place.
