Question

State the reaction occurring at the anode during electrolysis of
Copper sulphate solution using a copper anode.

Answer 1

Copper metal and oxygen gas are the end products of electrolyzing copper sulphate solution using inert electrodes (carbon/graphite or platinum). we can view the electrolysis products using the simple apparatus (above left figure) and inert carbon (graphite) electrodes.

Step1: Complete the reaction.

Copper sulphate solution using a copper anode.

$\mathrm{Cu}\left(s\right)-2{\mathrm{e}}^{-}\to {\mathrm{Cu}}^{2+}\left(aq\right)$

The copper atoms at the anode ionize to form ${\mathrm{Cu}}^{2+}$ ions and enter the copper sulphate solution.
