Which of the following behaves as both oxidising and reducing agents ?
1 \(\mathrm{H}_{2} \mathrm{SO}_{4}\)
2 \(\mathrm{SO}_{2}\)
3 \({{\rm{H}}_{\rm{2}}}{\rm{S}}\)
4 \(\mathrm{HNO}_{3}\)
Explanation:
In \({\rm{S}}{{\rm{O}}_{\rm{2}}}\), S is in +4 oxidation state which can be increased or decreased by gain or loss of electrons. Hence \({\rm{S}}{{\rm{O}}_{\rm{2}}}\) can act as oxidising and reducing agent.

Which statement is correct?
1 \(\mathrm{SO}_{2}\) dissolve in water & forms sulphurous acid
2 \(\mathrm{SO}_{2}\) has \({\rm{4p\pi - d\pi }}\) bonds
317008
Assertion : Reaction of \(\mathrm{SO}_{2}\) and \(\mathrm{H}_{2} \mathrm{~S}\) in the presence of \(\mathrm{Fe}_{2} \mathrm{O}_{3}\) catalyst gives elemental sulphur. Reason : \(\mathrm{SO}_{2}\) is a reducing agent.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect.
Explanation:
\(\mathrm{H}_{2} \mathrm{~S}\) and \(\mathrm{SO}_{2}\) react as follows: In this reaction, \(\mathrm{SO}_{2}\) is oxidising agent and oxidises \(\mathrm{H}_{2} \mathrm{~S}\) into sulphur. Thus, Assertion is correct but Reason is incorrect.
