Electrolysis of copper transfers copper atoms from an impure copper anode to a pure copper cathode, leaving the impurities behind. Unrefined copper is about 99 % pure. It contains traces of metals such as Fe, Zn, Ag, Au, and Pt. The purity can be increased to % by electrolytic refining in a cell similar to that shown below. A thin sheet of high purity Cu serves as the cathode. The anode

In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purer.

4. The electrolysis of copper(II) sulfate solution The electrolyte copper(II) sulfate, provides a high concentration of copper(II) ions Cu 2+ and sulfate ions SO 4 2– to carry the current during the electrolysis process. There are small concentrations of hydrogen ions H + and hydroxide ions (OH –) from the self ionisation of water itself, but these can be ignored in this experiment.
