Which of the following substances acts as an oxidising as well as a reducing agent?

A

`Na_2O`

B

`SnCI_2`

C

`Na_2O_2`

D

`NaNO_2`

Text Solution

Verified by Experts

The correct Answer is:
D
(d) In `Na_20, SnCl_2`, and `Na_2O2`, central atom is either in lowest or highest oxidation state, so it can function either as an oxidising or a reducing agent but not both. However, the oxidation state of N in `NaNO_2`, is +3 which lies between its highest (+5) and lowest (-3) values.
