During the electrolysis of aqueous sodium chloride the cathodic reaction is

A

Oxidation of `Cl^(-)` ion

B

Oxidation 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
`2H^(+)+2e^(-)rarrH_(2)`
`H^(+)` undergo reduction in preference to `Na^(+)` because of greater potential of H is les it gets liberated .
