Question

What will happen during the electrolysis of aqueous solution of CuSO₄ by using platinum electrodes?

Moderate

A

Copper will deposit at cathode
B

Copper will deposit at anode
C

Oxygen will be released at anode
D

Copper will dissolve at anode

Solution

For electrolysis of aqueous solution of CuSO₄
$\begin{aligned} {CuSO}_{4} (aq) ⟶ {Cu}^{2 +} + {SO}_{4}^{2 -} \\ H_{2} O ⟶ 2 H^{+} + O^{2 -} \end{aligned}$
$\begin{array}{l} Atanode 2 O^{2 -} ⟶ O_{2} + 2 e^{-} \\ Atcathode {Cu}^{2 +} + 2 e^{-} ⟶ Cu (s) \end{array}$
