Consider the reaction: H2SO3 (aq) + Sn^(...

Consider the reaction: `H_2SO_3 (aq) + Sn^(4+)(aq) + H_2O(l) to Sn^(2+)(aq) + HSO_4^(-)(aq) + 3H^(+)(aq)` Which of the following statements is correct?

A

`Sn^(4+)` is the oxidizing agent because it undergoes oxidation

B

`Sn^(4+)` is the reducing agent because it undergoes oxidation

C

`H_2SO_3` is reducing agent because it undergoes oxidation

D

`H_2SO_3` is the oxidising agent because it undergoes reduction

Text Solution

Verified by Experts

The correct Answer is:
C
`H_2SO_3` itself gets oxidized hence acts as a reducing agent while `Sn^(2+)` being reduced to +2 oxidation state acts as an oxidizing agent.
