Question

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)`.

Answer 1

Correct Answer - 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)`)
