A solution of sodium sulphate in water is electrolysed using inert electrodes, The products at the cathode and anode are respectively.

A

`H_(2),O_(2)`

B

`O_(2),H_(2)`

C

`O_(2),Na`

D

`O_(2),SO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
At anode `2H_(2)OtoO_(2)+4H^(+)+4e^(-)` (not `SO_(4)^(2-))`
At cathode: `2H_(2)O+2e^(-)toH_(2)+2OH^(-)` (not `Na^(+))`
