Assertion (A): `HNO_(3)` acts only as an oxidising agent, while `HNO_(2)` acts both as an oxidising agnet and a reducing agent.
Reason (R ): The oxidation number of `N` in `HNO_(3)` is maximum.

A

Statement 1 is true, statement 2 is true, statement 2 is a correct explanation for statement 4

B

Statement 1 is true, statement 2 is true, statement 2 is not a correct explanation for statement 4

C

Statement 1 is true, statement 2 is false

D

Statement 1 is false, statement 2 is true

Text Solution

Verified by Experts

The correct Answer is:
A
Both (A) and (2) are correct, and (2) is the correct explanation for (1) since the oxidation number of N in `HNO_(3)` is maximum (+5), therefore, it can only decrease. Hence, `HNO_(3)` acts as an oxidising agent. In `HNO_(2)`, the oxidation number of N is +3, so it can increase by losing electrons or can decrease by accepting electrons. Therefore, `HNO_(2)` acts both as an oxidising as well as a reducing agent.
