A dilute aqueous solution of Na(2)SO(4) ...

A dilute aqueous solution of `Na_(2)SO_(4)` is electrolyzed using platinum electrodes. The products at the anode and cathode are :

A

`O_(2),H_(2)`

B

`S_(2)O_(8)^(2-),Na`

C

`O_(2),Na`

D

`S_(2)O_(8)^(2-),H_(2)`.

Text Solution

Verified by Experts

The correct Answer is:
A
Factual question (only a 50% aquesous solution of `H_(2)SO_(4)` on electrolysis using inert electrodes gives `S_(2)O_(3)^(2-)` ions and `H_(2)`)
