In the reaction `2Ag+2H_(2)SO_(4)rarrAg_(2)SO_(4)+2H_(2)O+SO_(2),H_(2)SO_(40`acts as `a//an`

A

Oxidising agent

B

Reducing agent

C

Catalyst

D

Acid as well as oxidant

Text Solution

Verified by Experts

The correct Answer is:
D
In `2Ag+H_(2)SO_(4)rarrAg_(2)SO_(4)+2H_(2)O+SO_(2)`
`H_(2)SO_(4)` act as acid (S retain it O.N. = +6 in `Ag_(2)SO_(4)`) as well as an oxidising agent
`(overset(+6)(H_(2)SO_(4))rarroverset(+4)(SO_(2)))`.
