describe electrolitic refining of copper​

Answer 1

⭐️Answer⭐️

Electrolytic refining of copper

In the process of electrolytic refining of copper, the electrolyte used is acidified copper sulphate.

Impure metal is made as an anode and pure metal is made as a cathode.

On passing the electric current through the electrolyte, the impure metal from anode dissolves into the electrolyte solution

and pure metal from copper sulphate solution deposits on the cathode.

• At Anode:  Cu → Cu2+  + 2e-

• At Cathode: Cu2+  + 2e- → Cu

The soluble impurities go into the solution and insoluble impurities settle down at the bottom of an anode and are known as anode mud.
