On electrolysis of a solution of dilute `H_(2)SO_(4)` between platinum electrodes , the gas evolved at the anoe is

A

`SO_(2)`

B

`SO_(3)`

C

`O_(2)`

D

`H_(2)`

Text Solution

Verified by Experts

The correct Answer is:
c
Oxidation potential of `H_(2)Ogt` Oxidation potential of `SO_(4)^(2-)`
So oxidation of `H_(2)O` occurs at anode and gives `O_(2)(g)`.
