Q. What will be pH of aqueous solution of electrolyte in electrolytic cell during electrolysis of $CuSO_{4}(aq)$ between graphite electrodes?
A) pH = 14.0
B) pH > 7.0
C) pH < 7.0
D) pH = 7.0
Explanation
(c)
$pH\ < 7$; Aqueous solution of $Cu{SO}_{4}\$is acidic in nature. Furthermore some drops of $H_{2}{SO}_{4}$ is also added during electrolysis.
