If electrolysis of aqueous CuSO $_{4}$ solution is carried out using Cu-electrodes, the reaction taking place at the anode is

Options:

Answer:

Solution:

Electrolysis of copper sulphate solution using Cu-electrodes, Ions present : $Cu^{2 +}, H^{+}, SO_{4}^{2 -}, OH^{-}$ At cathode $Cu^{2 +} (a q) + 2 e^{-} \to Cu (s)$ At anode $Cu (s) - 2 e^{-} \to Cu^{2 +} (a q)$ So, the option (d) is correct answer.
