  • Describe the method used for refining copper metal

    Copper metal is refined by using electrolytic method with impure copper metal as anode and the pure copper metal strip as cathode. The electrolyte is acidified copper sulphate solution. Copper dissolves from the anode into the electrolyte and get reduced and deposited on the cathode as pure metal. Anode: Cu → Cu 2+ + 2e. Cathode: Cu 2+ + 2e
