Question

A strip of impure copper metal is given to you. Describe briefly, how you will purify it by using the chemical of electric current.

Answer 1

Answer:

In the purification of copper by electrolytic refining, the strip of impure copper metal is made the anode and a strip of pure copper metal is the cathode. A solution of copper sulphate is used as the electrolyte. When current is passed through the electrolyte, pure copper from the anode dissolves in the electrolyte.
