The product obtained at anode when 50% `H_(2)SO_(4)` aqueous soltuion is electrolysed using Platinum electrodes is :

A

`H_(2)SO_(3)`

B

`H_+(2)S_(2)OB`

C

`O_2`

D

`H_(2)`

Verified by Experts

The correct Answer is:

B

50% `H_(2)SO^_(4)` is very concentrated solution , so , oxidation of `SO_(4)^(2-) rightarrow S_(2)O_(8)^(2-)` takes place.
