Question

The compound that cannot act both as oxidising and reducing agent is (A) HNO2 (B) H2O2 (C) H2SO3 (D) H3PO4

Tardigrade Admin · Accepted Answer

H2O2- 1 H2SO3+ 4 overset+ 3H N O2 As in H3PO4 phosphorous is in maximum oxidation state +5 so it can not undergo oxidation or can be reduced only so it is an oxidant only.

Q. The compound that cannot act both as oxidising and reducing agent is

$H N O_{2}$

$H_{2} O_{2}$

$H_{2} S O_{3}$

$H_{3} P O_{4}$

$H_{2} O_{2}^{- 1}$ $H_{2} S O_{3}^{+ 4}$ $H N O_{2} + 3$
As in $H_{3} P O_{4}$ phosphorous is in maximum oxidation state +5 so it can not undergo oxidation or can be reduced only so it is an oxidant only.
