purification of copper by electrolysis

Extraction of Metals. Extraction of Copper - Purification by Electrolysis. High purity copper is needed to make electrical wires. The anode is a block of impure copper. The cathode is a thin piece of pure copper. The electrolyte is copper sulfate. When electricity is passed through the cell copper is dissolved at the anode by oxidation and Cu 2+ ions go into solution.

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. The cathode is a thin sheet of pure. The electrolyte used is an aqueous solution of a soluble salt of the pure metal at the anode, e.g: CuSO 4.

The electrolyte (solution the ions travel through) is a solution of copper (II) sulphate (CUSO 4). During electrolysis, copper (II) ions leave the impure copper anode and since they are positive, they are attracted to the negative cathode. Here they pick up the two electrons that are needed to form a copper metal, and this builds up pure copper.
