Neutral ferric chloride is added to the aqueous solution of acetate. The blood red colour is obtained, it is due to the compound

Options

A. `Fe(OH)_(2)`
B. `Fe(OH)_(3)`
C. `[Fe_(3)(CH_(3)COO)_(6)(OH)_(2)]^(+)`
D. `Fe(OH)_(2)(CH_(3)COO)`

Answer

To solve the question regarding the formation of a blood red color when neutral ferric chloride is added to an aqueous solution of acetate, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components**:
- Neutral ferric chloride is represented as FeCl3. It contains ferric ions (Fe³⁺) and chloride ions (Cl⁻).
- Acetate ions are represented as CH3COO⁻.

2. **Understanding the Reaction**:
- When neutral ferric chloride (FeCl3) is added to an acetate solution, the ferric ions (Fe³⁺) interact with the acetate ions (CH3COO⁻).

3. **Chemical Reaction**:
- The reaction can be represented as:
\[ \text{Fe}^{3+} + 6 \text{CH}_3\text{COO}^- \rightarrow \text{Fe(CH}_3\text{COO)}_6^{3+} + 3 \text{H}_2\text{O} \]
- This shows that one ferric ion reacts with six acetate ions to form a complex.

4. **Formation of the Blood Red Color**:
- The complex formed, \(\text{Fe(CH}_3\text{COO)}_6^{3+}\), is responsible for the blood red color observed in the solution. This complex has distinct optical properties that result in the red coloration.

5. **Conclusion**:
- The blood red color is due to the formation of the ferric acetate complex, \(\text{Fe(CH}_3\text{COO)}_6^{3+}\).

### Final Answer:
The blood red color is due to the formation of the compound \(\text{Fe(CH}_3\text{COO)}_6^{3+}\).
