Question

By the electrolysis of aqueous solution of CuSO₄ , the products obtained at both the electrodes are

(a) O₂ at anode and H₂ at cathode

(b) H₂ at anode and Cu at cathode

(c) O₂ at anode and Cu at cathode

(d) H₂S₂O₈ at anode and O₂ at cathode

Answer 1

Correct option (c) O₂ at anode and Cu at cathode

Explanation:

Oxygen is oxidised at anode while Cu²⁺ is reduced at cathode. Therefore. copper deposits on cathode and oxygen is evolved at anode.
