Electrolytic refining of Copper

In electrolytic refining, the impure metal and a strip of pure metal is used. The impure metal is made to act as an anode and pure metal is made to act as a cathode. They are dipped in an electrolytic bath which contains the soluble salt of the same metal. As electricity is passed through the solution, the less basic metal moves towards the anode mud leaving the more basic metal in the solution. In the process of electrolytic refining, the thickness of cathode increases with time.
