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

A

`Na_(2)O`

B

`SnCl_(2)`

C

`Na_(2)O_(2)`

D

`NaNO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`NaNO_(2)` (Sodium nitrite) acts both as oxidising as well as reducing agent because N atom is in +3 oxidation state in it (intermediate oxidation state).
Oxidising property:
`NaNO_(2)+2KI+2H_(2)SO_(4)toNa_(2)SO_(4)+K_(2)SO_(4)+2NO+2H_(2)O+I_(2)`
Reducing Property :
`H_(2)O_(2)+NaNO_(2)toNaNO_(3)+H_(2)O`
