The passage of current through a solution of certain electrolyte results in the evolution of `H_2`(g) at cathode and `Cl_2`(g) at anode. The electrolytic solution is :

A

Water

B

`H_(2)SO_(4)`

C

Aqueous NaCl

D

Aqueous `CuCl_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
Aqueous NaCl undergoes electrolysis and liberates `H_(2)` at cathode and chlorine at anode.
