Question

Select the correct answer from the list given in brackets.
The ion which is discharged at the anode during the electrolysis of copper sulphate solution using copper electrodes as anode and cathode $({\mathrm{Cu}}^{2+},{\mathrm{OH}}^{-},{{\mathrm{SO}}_4}^{2-},{\mathrm{H}}^{+}).$.

Answer 1

Copper ions are discharged:-

1. Copper is an active electrode.
2. Thus it loses electrons and in this process it self ionizes in order to form ${\mathrm{Cu}}^{2+}\mathrm{ions}$.

Therefore, ${\mathrm{Cu}}^{2+}\mathrm{ions}$ is discharged at the anode during the electrolysis of Copper sulphate solution using Copper electrodes as anode and cathode.
