Explanation

To analyze the given reaction and determine the oxidation states of the elements involved, we can follow these steps:

### Step-by-Step Solution:

1. **Write the Reaction**:
The reaction given is:
\[ \text{SnCl}_2 + 2\text{FeCl}_3 \rightarrow \text{SnCl}_4 + 2\text{FeCl}_2 \]

2. **Determine Oxidation States**:
- For **SnCl₂**:
- Let the oxidation state of Sn be \( x \).
- The equation for the oxidation state is:
\[ x + 2(-1) = 0 \implies x - 2 = 0 \implies x = +2 \]
- Thus, the oxidation state of Sn in SnCl₂ is +2.

- For **FeCl₃**:
- Let the oxidation state of Fe be \( y \).
- The equation for the oxidation state is:
\[ y + 3(-1) = 0 \implies y - 3 = 0 \implies y = +3 \]
- Thus, the oxidation state of Fe in FeCl₃ is +3.

- For **SnCl₄**:
- The oxidation state of Sn is:
\[ z + 4(-1) = 0 \implies z - 4 = 0 \implies z = +4 \]
- Thus, the oxidation state of Sn in SnCl₄ is +4.

- For **FeCl₂**:
- The oxidation state of Fe is:
\[ w + 2(-1) = 0 \implies w - 2 = 0 \implies w = +2 \]
- Thus, the oxidation state of Fe in FeCl₂ is +2.

3. **Identify Oxidation and Reduction**:
- **Oxidation**: An increase in oxidation state.
- Sn goes from +2 (in SnCl₂) to +4 (in SnCl₄). This is an increase in oxidation state, indicating that Sn is oxidized.

- **Reduction**: A decrease in oxidation state.
- Fe goes from +3 (in FeCl₃) to +2 (in FeCl₂). This is a decrease in oxidation state, indicating that Fe is reduced.

4. **Identify the Oxidizing and Reducing Agents**:
- The substance that gets oxidized (SnCl₂) acts as a reducing agent.
- The substance that gets reduced (FeCl₃) acts as an oxidizing agent.

5. **Conclusion**:
- SnCl₂ is oxidized to SnCl₄.
- FeCl₃ is reduced to FeCl₂.
- Therefore, the correct statements are:
- SnCl₂ is oxidized.
- FeCl₃ acts as an oxidizing agent.

### Final Answer:
- SnCl₂ is oxidized and FeCl₃ acts as an oxidizing agent.
