When CuSO4 is electrolysed using platinum electrodes?

Question

When CuSO4 is electrolysed using platinum electrodes? (A) Copper is liberated at cathode, sulphur at anode (B) Copper is liberated at cathode, oxygen at anode (C) Sulphur is liberated at cathode, oxygen at anode (D) Oxygen is liberated at cathode, copper at anode

Tardigrade Admin · Accepted Answer

During electrolysis, copper is deposited at the cathode while oxygen is liberated at anode. The following reactions occur at the electrodes
At anode

2 H_{2} O ⟶ 4 H^{+} + O_{2} + 4 e^{-}

(Oxidation)
At cathode

C u^{2 +} + 2 e^{-} ⟶ C u (s)

(Reduction)

Q. When CuSO4​ is electrolysed using platinum electrodes?

Copper is liberated at cathode, sulphur at anode

Copper is liberated at cathode, oxygen at anode

Sulphur is liberated at cathode, oxygen at anode

Oxygen is liberated at cathode, copper at anode

During electrolysis, copper is deposited at the cathode while oxygen is liberated at anode. The following reactions occur at the electrodes At anode 2H2​O⟶4H++O2​+4e−(Oxidation) At cathode Cu2++2e−⟶Cu(s) (Reduction)

Q. When $C u S O_{4}$ is electrolysed using platinum electrodes?

During electrolysis, copper is deposited at the cathode while oxygen is liberated at anode. The following reactions occur at the electrodes
At anode $2 H_{2} O ⟶ 4 H^{+} + O_{2} + 4 e^{-}$ (Oxidation)
At cathode $C u^{2 +} + 2 e^{-} ⟶ C u (s)$ (Reduction)
