From the Electrolysis of concentrated copper(ii) sulphate

2017/7/10You will get oxygen and metallic copper. You have a mixture of Cu^2+, SO_4^2-, and H_2O. Something must be oxidized, and something must be reduced, so you consult a table of standard reduction potentials like the one below to find suitable candidates, The only candidate for reduction in the table is Cu^2+(aq) + 2e^- → Cu(s); +0.34 V Now,we look for candidates for

Electrolysis of solutions with inert electrodes
