Consider the reaction

Question:

Consider the reaction

$\mathrm{H}_{2} \mathrm{SO}_{3(a q)}+\mathrm{S}_{(a \mathrm{aq})}^{4+}+\mathrm{H}_{2} \mathrm{O}_{(1)} \rightarrow \mathrm{S}_{(a q)}^{2+}+\mathrm{HSO}_{4(a q)}^{-}+3 \mathrm{H}_{\text {(aq) }}^{+}$

Which of the following statements is correct?

  1. $\mathrm{H}_{2} \mathrm{SO}_{3}$ is the reducing agent because it undergoes oxidation

  2. $\mathrm{H}_{2} \mathrm{SO}_{3}$ is the reducing agent because it undergoes reduction

  3. $\mathrm{Sn}^{4+}$ is the reducing agent because it undergoes oxidation
