Vedclass · Answer

(D) During the electrolysis of aqueous $CuSO_4$ solution using $Cu$ electrodes, the following ions are present in the solution: $Cu^{2+}$, $H^{+}$, $SO_{4}^{2-}$, and $OH^{-}$.At the cathode, $Cu^{2+}$ ions are reduced: $Cu^{2+}_{(aq)} + 2e^{-} \rightarrow Cu_{(s)}$.At the anode, the $Cu$ electrode itself undergoes oxidation because it is an active electrode: $Cu_{(s)} - 2e^{-} \rightarrow Cu^{2+}_{(aq)}$.Therefore, the correct option is $D$.

If electrolysis of aqueous $CuSO_4$ solution is carried out using $Cu$ electrodes, the reaction taking place at the anode is:
