Which of the following is anodic reaction.

A

`SO_(4)^(2-)+H_(2)O rarr H_(2)SO_(4)+1//2O_(2)+2e^(-)`

B

`H^(o+)+e^(-)rarr 1//2OH_(2)`

C

`Ag^(o+)+e^(-) rarr Ag`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
a
At anode, oxidation occurs. So oxidatin reaction is only is `(a)`
