Question
Which of the following behaves as both oxidising and reducing agents
Answer: Option B
:
B
In SO2, sulphur has a +4 oxidation state. In H2SO4, Sulphur exhibits its highest oxidation state of +6.
On the other hand - in H2S, sulphur exists in its lowest -2 oxidation state. Thus, we can surmise
that SO2 could act as both an oxidising agent as well as a reducing agent. Nitrogen exhibits its highest oxidation
state of +5 in HNO3.
