During the electrolysis of aqueous sodium chloride the cathodic reaction is

A

Oxidation of `Cl^(-)` ion

B

Reduction of `Na^(+)` ion

C

Reduction of `H_(2)O`

D

Oxidation of `H_(2)O`

Text Solution

Verified by Experts

The correct Answer is:
C

At the cathode `H_(2)O` is reduced more easily than `Na^(+)` ions . (SRP of `H_(2)O gt Na^(+)`)
