What happens to Fe²⁺ in the following reaction? Sn⁴⁺ + Fe²⁺ → Sn³⁺ + Fe³⁺ (A) It undergoes oxidation and gains electrons - HSC - SSCE Chemistry - Question 4 - 2015 - Paper 1

In the given reaction, we have:

$$ext{Sn}^{4+} + ext{Fe}^{2+} ightarrow ext{Sn}^{3+} + ext{Fe}^{3+}$$

To determine what happens to Fe²⁺, we need to analyze the oxidation states:

• Sn⁴⁺ is being reduced to Sn³⁺, as it gains an electron.
• Fe²⁺ is being oxidized to Fe³⁺, which means it loses an electron.

Thus, Fe²⁺ undergoes oxidation and loses electrons. Therefore, the correct answer is (C) It undergoes oxidation and loses electrons.
