Consider the reaction:

H2SO3(aq) + Sn4+(aq) + H2O(l) → Sn2+(aq) + HSO4-(aq) + 3H+(aq)

Which of the following statements is correct?

(a) Sn4+ is the oxidizing agent because it undergoes oxidation

(b) Sn4+ is the reducing agent because it undergoes oxidation

(c) H2SO3 is the reducing agent because it undergoes oxidation

(d) H2SO3 is the reducing agent because it undergoes reduction

Correct answer: (c) H2SO3 is the reducing agent because it undergoes oxidation

Explanation:

(+4)H2SO3(aq) + Sn4+(aq) + H2O(l) → Sn2+(aq) + (+6)HSO4-(aq) + 3H+(aq)

Hence H2SO3 is the reducing agent because it undergoes oxidation.
