MCQ
Which compound acts as an oxidising as well as reducing agent
- ✓$S{O_2}$
- B$KMn{O_4}$
- C$A{l_2}{O_3}$
- D$Cr{O_3}$
✓
Answer
Correct option: A.
$S{O_2}$
a
(a) 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.
(a) 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 $S{O_2}$ behaves both as an oxidising as well as reducing agent.
