  • Electrolytic refining Oxford Reference

    The purification of metals by electrolysis. It is commonly applied to copper. A large piece of impure copper is used as the anode with a thin strip of pure copper as the cathode. Copper(II) sulphate solution is the electrolyte. Copper dissolves at the anode Cu Cu2++2e, and is deposited at the cathode. The net result is transfer of pure copper from anode to cathode.
