To investigate the electrolysis of copper(II) sulfate solution, and of sodium chloride solution, using inert (unreactive) electrodes.
Using inert electrodes made of carbon. Copper sulfate solution (CuSO4(aq)) contains the following ions: Cu2+ SO42-H+. O2-At the anode: 2O2- -2e- → ↑O2(g) - oxygen ions lose electrons to become oxygen gas. At the cathode: Cu2+ + 2e- → Cu - Copper ions gain electrons and become copper metal.
