If in chemical reaction, `Fe^(+2)` is converted into `Fe^(+3)`, then `Fe^(+2)` -

Options

A. Gain one electron
B. Loses one electron
C. Gains one proton
D. Loses one proton

Answer

To solve the question, we need to analyze the conversion of \( \text{Fe}^{+2} \) to \( \text{Fe}^{+3} \).

### Step-by-Step Solution:

1. **Identify the oxidation states**:
- In the reaction, \( \text{Fe}^{+2} \) has an oxidation state of +2.
- \( \text{Fe}^{+3} \) has an oxidation state of +3.

2. **Determine the change in oxidation state**:
- The change from +2 to +3 indicates that the iron is becoming more positive. This means it is losing electrons.

3. **Calculate the number of electrons lost**:
- To go from +2 to +3, \( \text{Fe}^{+2} \) must lose 1 electron.
- The equation can be represented as:
\[ \text{Fe}^{+2} \rightarrow \text{Fe}^{+3} + e^- \]
- Here, \( e^- \) represents the electron that is lost.

4. **Conclusion**:
- Therefore, \( \text{Fe}^{+2} \) loses 1 electron to become \( \text{Fe}^{+3} \).

### Final Answer:
- \( \text{Fe}^{+2} \) loses one electron.
