Identify reductant in following reaction. \(\mathrm{\mathrm{H}_{2} \mathrm{~S}+\mathrm{NO}_{2} \rightarrow \mathrm{H}_{2} \mathrm{O}+\mathrm{NO}+\mathrm{S}}\)
1 \({{\text{H}}_{\text{2}}}{\text{S}}\)
2 \(\mathrm{\mathrm{NO}_{2}}\)
3 \(\mathrm{\mathrm{NO}}\)
4 \(\mathrm{\mathrm{S}}\)
Explanation:
\({{\text{H}}_{\text{2}}}{\text{S}}\) undergoes oxidation \(\mathrm{(-2}\) to 0\(\mathrm{)}\). So reductant.

Assertion : \(\mathrm{Cl}_{2}\) gas bleaches the articles permanently. Reason : \(\mathrm{Cl}_{2}\) is a strong 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 Assertion is incorrect but Reason is correct.
Explanation:
\(\mathrm{Cl}_{2}\) is an effective oxidizing agent. When it comes into contact with various substances, it can cause oxidation reactions, leading to the removal of color from these materials. In the presence of moisture, \(\mathrm{Cl}_{2}\) exhibits its bleaching properties by oxidizing the substances. So the option (3) is correct

Which of the following acts as both oxidant and reductant?
1 \(\mathrm{\mathrm{HNO}_{3}}\)
2 \(\mathrm{\mathrm{HNO}_{2}}\)
3 Both \({\rm{HN}}{{\rm{O}}_{\rm{3}}}\,\,{\rm{\& }}\,\,{\rm{HN}}{{\rm{O}}_{\rm{2}}}\)
4 Neither \(\mathrm{\mathrm{HNO}_{3}}\) nor \(\mathrm{\mathrm{HNO}_{2}}\)
Explanation:
O.N. of \(\mathrm{\mathrm{N}}\) in \(\mathrm{\mathrm{HNO}_{2}}\) is +3 Max. O.N. of \(\mathrm{\mathrm{N}}\) is +5 Min. O.N. of \(\mathrm{\mathrm{N}}\) is \({\rm{ - 3}}\) Thus O.N. of \(\mathrm{\mathrm{N}}\) in \(\mathrm{\mathrm{HNO}_{2}}\) can show an increase or decrease as the case may be. That is why \(\mathrm{\mathrm{HNO}_{2}}\) acts as oxidant and reductant both. O.N. of \(\mathrm{\mathrm{N}}\) in \(\mathrm{\mathrm{HNO}_{3}}\) is +5 . Hence it can act only as an oxidant.
