In the electrolysis of which solution `OH^(-)` ions are discharged in preference to `Cl^(-)` ions?

A

Dilute NaCl

B

Very dilute NaCl

C

Fused NaCl

D

Solid NaCl.

Text Solution

Verified by Experts

The correct Answer is:
B
In very dilute solution of NaCl, the following reaction takes place on electrolysis.
Anode: `2OH^(-)rarrH_(2)O+1//2O_(2)+2e^(-)`
Cathode: `2H^(+)+2e^(-)rarrH_(2)`
