JEE : Electrolytic Refining
Electrolytic refining of Copper (Cu) In refining a metal such as copper by electrolysis, the crude metal is used as the anode that goes into the solution. The pure metal gets deposited on the cathode, which is called electrolytic refining. In an electrolytic tank, the electrolyte used is acidified copper sulphate (CuSO 4 + dilute H 2 SO 4).
