Purification of Copper Edexcel GCSE Chemistry Revision Notes

The electrolysis of CuSO 4 using graphite rods produces oxygen and copper. By changing the electrodes from graphite to pure and impure copper, the products can be changed at each electrode. Electrolysis can be used to purify metals by separating them from their impurities. In the set-up, the impure metal is always the anode, in this case the impure copper.
