Question

Which compound acts as an oxidising as well as reducing agent? (A) SO2 (B) MnO2 (C) Al2O3 (D) CrO3

Tardigrade Admin · Accepted Answer

The minimum and maximum oxidation number of S are -2 and +6 respectively. Since the oxidation number of S in SO2 is +4, therefore it can be either increased or decreased. Therefore behaves both as an oxidising and as reducing agent.

Q. Which compound acts as an oxidising as well as reducing agent?

$S O_{2}$

$M n O_{2}$

$A l_{2} O_{3}$

$C r O_{3}$

The minimum and maximum oxidation number of $S$ are $- 2$ and $+ 6$ respectively. Since the oxidation number of $S$ in $S O_{2}$ is $+ 4$ , therefore it can be either increased or decreased. Therefore behaves both as an oxidising and as reducing agent.
