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

Text Solution

Verified by Experts

The correct Answer is:
B
In case of very dilute solution of `NaCl`, electrolysis brings in the following changes.
Anode: `2OH^(-)toH_(2)O+(1)/(2)O_(2)+2e^(-)`
Cathode: `2H^(+)+2etoH_(2)`.
