The reaction occurring at the cathode during the electrolysis of copper sulphate using inert electrodes is given by the equation
- (A)
\text{Cu} \rightarrow \text{Cu}^{2+} + 2\text{e}^- - (B)
\text{Cu}^{2+} + 2\text{e}^- \rightarrow \text{Cu} - (C)
2\text{H}^+ + 2\text{e}^- \rightarrow \text{H}_2 - (D)
4\text{OH}^- - 4\text{e}^- \rightarrow 2\text{H}_2\text{O} + \text{O}_2
