Among these, \(\mathrm{\mathrm{O}_{3}}\) has maximum value of standard reduction potential \(\mathrm{\left(\mathrm{E}^{\circ}=+2.07 \mathrm{~V}\right)}\), so it is strongest oxidising agent.

The compound that can work both as an oxidising as well as a reducing agent is
1 \(\mathrm{\mathrm{KMnO}_{4}}\)
2 \(\mathrm{\mathrm{H}_{2} \mathrm{SO}_{4}}\)
3 \(\mathrm{\mathrm{BaO}_{2}}\)
4 \(\mathrm{\mathrm{H}_{2} \mathrm{O}_{2}}\)
Explanation:
\(\mathrm{\mathrm{In}_{2} \mathrm{H}_{2} \mathrm{O}_{2}}\) the O.N. of \(\mathrm{\mathrm{O}}\) is \({\rm{ - 1}}\) which can be increased to 0 or decreased to \({\rm{ - 2}}\) hence \(\mathrm{\mathrm{H}_{2} \mathrm{O}_{2}}\) can work as reducing and oxidising agent.

Assertion : Sn reacts with \(\mathrm{HCl}\) to produce \(\mathrm{H}_{2}\) gas. Reason : \(\mathrm{Sn}\) is a better reducing agent than \(\mathrm{H}_{2}\).
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:
In the reaction of \(\operatorname{tin}(\mathrm{Sn})\) with hydrochloric acid, tin acts as a better reducing agent than hydrogen due to its higher oxidation potential, facilitating the reduction of hydrogen ions \(\left(\mathrm{H}^{+}\right)\) to form hydrogen gas \(\left(\mathrm{H}_{2}\right)\) while undergoing oxidation itself. So the option (1) is correct.

Assertion : \(\mathrm{Na}^{+}\)ion cannot be further oxidised or reduced by water. Reason : When \(\mathrm{NaCl}\) is dissolved in water sodium ion is hydrolysed.
1 Assertion is correct but Reason is incorrect.
2 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
3 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
4 Assertion is incorrect but Reason is correct.
Explanation:
When \(\mathrm{NaCl}\) is dissolved in water, the \(\mathrm{Na}+\) ions are hydrated and not hydrolysed. \(\mathrm{NaCl}+\mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{NaOH}+\mathrm{HCl}\) So the option (3) is correct.
Among these, \(\mathrm{\mathrm{O}_{3}}\) has maximum value of standard reduction potential \(\mathrm{\left(\mathrm{E}^{\circ}=+2.07 \mathrm{~V}\right)}\), so it is strongest oxidising agent.
