Question
Which of the following molecules can act as an oxidising as well as a reducing agent?SO2SO2HIMnO2
Solution
The molecule that can act as both an oxidising and a reducing agent is SO2.
Here's why:
-
Oxidising Agent: SO2 can accept electrons from another substance, thus getting reduced itself and acting as an oxidising agent. The reaction is as follows: SO2 + 2e- -> S + O2
-
Reducing Agent: SO2 can also donate electrons to another substance, thus getting oxidised itself and acting as a reducing agent. The reaction is as follows: SO2 -> SO3 + 2e-
Therefore, SO2 can act as both an oxidising and a reducing agent.
