In which of the following reactions HNO3 will not act as an oxidising agent?

A

`HNO_3 + H_2SO_4 rarr `

B

`HNO_3 + FeSO_4 + H_2SO_4 rarr`

C

`KI + HNO_3 rarr `

D

`Au + HNO_3 rarr`

Text Solution

Verified by Experts

The correct Answer is:
A
`HNO_(3) + H_2SO_4 rarr NO_(2)^(+) +HSO_(4)^(-) + H_2O`
In this reaction `HNO_3` is acting as `OH^-` donor and `H_2SO_4` as `H^+` donor. This is not a redox reaction.
