Consider the reaction : H 2 SO 3 aq + Sn aq 4 + + H 2 O l ⁡ → Sn aq 2 + + HSO 4 aq - + 3 H aq +…
Which of the following statements is correct ?
- Sn4+ is the oxidizing agent because it undergoes oxidation
- Sn4+ is the reducing agent because it undergoes oxidation
- H2SO3 is the reducing agent because it undergoes reduction
- H2SO3 is the reducing agent because it undergoes oxidation
