Electrorefining Of Copper In The Industry

Electrorefining - Purifying Copper in Industry - Activity

An impure sample of copper may be purified by using the sample as the anode in an electrolysis cell with a pure copper cathode and copper(II) sulfate solution as the electrolyte. In this activity, we first examine the behaviour of an electrolytic cell in which both electrodes are made of pure copper.
