`FeCl_(3)+Na_(3)PO_(4) to FePO_(4)darr+3NaCl`

Options

A. For precipitate formation formation reaction
B. For precipitate dissolution reaction
C. For precipitate exchange reaction
D. For no reaction

Answer

To solve the given reaction \( \text{FeCl}_3 + \text{Na}_3\text{PO}_4 \rightarrow \text{FePO}_4 \downarrow + 3\text{NaCl} \), we will analyze the components involved and the type of reaction that occurs.

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants are iron(III) chloride (\( \text{FeCl}_3 \)) and sodium phosphate (\( \text{Na}_3\text{PO}_4 \)).

2. **Identify the Products**:
- The products of the reaction are iron(III) phosphate (\( \text{FePO}_4 \)), which is a precipitate, and sodium chloride (\( \text{NaCl} \)).

3. **Determine the Reaction Type**:
- In this reaction, \( \text{FeCl}_3 \) and \( \text{Na}_3\text{PO}_4 \) react to form \( \text{FePO}_4 \) and \( \text{NaCl} \).
- The formation of \( \text{FePO}_4 \) indicates that a solid precipitate is formed from the reaction of two aqueous solutions.

4. **Analyze the Precipitate**:
- The product \( \text{FePO}_4 \) is indicated with a downward arrow (\( \downarrow \)), which signifies that it is a precipitate that forms and settles out of the solution.

5. **Conclusion**:
- Since a precipitate is formed from the reaction of two soluble reactants, this reaction is classified as a **precipitate formation reaction**.

### Final Answer:
The correct classification of the reaction \( \text{FeCl}_3 + \text{Na}_3\text{PO}_4 \rightarrow \text{FePO}_4 \downarrow + 3\text{NaCl} \) is a **precipitate formation reaction**.
