Question

Which of the following reactions shows the reducing property of $\mathrm{SO}_2$ ? \ (i) $\mathrm{Cl}_2+\mathrm{SO}_2 \rightarrow \mathrm{SO}_2 \mathrm{Cl}_2$ \(ii) $2 \mathrm{H}_2 \mathrm{~S}+\mathrm{SO}_2 \rightarrow 3 \mathrm{~S}+2 \mathrm{H}_2 \mathrm{O}$ \(iii) $2 \mathrm{FeCl}_3+\mathrm{SO}_2+2 \mathrm{H}_2 \mathrm{O} \rightarrow 2 \mathrm{FeCl}_2+\mathrm{H}_2 \mathrm{SO}_4 +2 \mathrm{HCl}$ \(iv) $\mathrm{SO}_2+\mathrm{H}_2 \mathrm{O} \rightarrow \mathrm{H}_2 \mathrm{SO}_3$
