Assertion (A): The electrolysis of NaCl ...

Assertion `(A):` The electrolysis of `NaCl` solution gives `H_(2)(g)` at cathode and `Cl_(2)(g)` at anode.
Reason `(R) : Cl_(2)` has higher oxidation potential than `H_(2)O`

A

If both assertion and reason are true, and reason is the true explanation of the assertion

B

if both assertion and reason are true, but reason is not the true explanation of the assertion.

C

if assertion is true, but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
