Question

Which one of the following is not a reducing agent?
a) NaNO2
b)NaNO3
c) HI
d) SnCl2​

Answer 1

The answer for the following which is not a reducing agent  is "b" NaNO3 because

Nitrogen is in its highest oxidation state .

Answer 2

Answer:

Sodium nitrate NaNO3 is a strong oxidizing agent, it is not a reducing agent.

Explanation:

Oxidizing agents : Those chemical substances which can undergo reduction are termed as oxidizing states. The central atom is present in higher oxidation state and after receiving electrons , it moves to lower oxidation. Hence, it is reduced. They oxidise other substances. For example- Potassium Permanganate, Potassium dichromate, and Sodium nitrate.

Reducing agents : They undergo oxidation by losing electrons. In terms of oxidation state, they move from lower oxidation state to the higher oxidation state. They reduce other substances hence called as reducing agent.

In given options, Sodium nitrate is an oxidizing substance as nitrogen atoms can not lose any more electrons. So, the correct option is NaNO3.
