For the following redox reaction, find the correct statement.
$\text{Sn}^{2+} + 2\text{Fe}^{3+} \rightarrow \text{Sn}^{4+} + 2\text{Fe}^{2+}$
$\text{Sn}^{2+} + 2\text{Fe}^{3+} \rightarrow \text{Sn}^{4+} + 2\text{Fe}^{2+}$
- Correct answerA$\text{Sn}^{2+}$ is undergoing oxidation.
- B$\text{Fe}^{3+}$ is undergoing oxidation.
- CIt is not a redox reaction.
- DBoth $\text{Sn}^{2+}$ and $\text{Fe}^{3+}$ are oxidized.
Solution
The given reaction is $\text{Sn}^{2+} + 2\text{Fe}^{3+} \rightarrow \text{Sn}^{4+} + 2\text{Fe}^{2+}$
The oxidation state of $\text{Sn}$ increases from $+2$ to $+4$, which indicates that $\text{Sn}^{2+}$ undergoes oxidation.
The oxidation state of $\text{Fe}$ decreases from $+3$ to $+2$, which indicates that $\text{Fe}^{3+}$ undergoes reduction.
Therefore, $\text{Sn}^{2+}$ is undergoing oxidation.
Answer: $\text{Sn}^{2+}$ is undergoing oxidation.
The oxidation state of $\text{Sn}$ increases from $+2$ to $+4$, which indicates that $\text{Sn}^{2+}$ undergoes oxidation.
The oxidation state of $\text{Fe}$ decreases from $+3$ to $+2$, which indicates that $\text{Fe}^{3+}$ undergoes reduction.
Therefore, $\text{Sn}^{2+}$ is undergoing oxidation.
Answer: $\text{Sn}^{2+}$ is undergoing oxidation.
Hence, the correct answer is option: 'A'.
