Aqueous solution of `FeSO_(4)` does not produce precipitate with:

Options

A. `NaOH`
B. `NH_(3)` solution
C. `Na_(2)CO_(3)`
D. None of these

Explanation

To solve the question regarding which compound does not produce a precipitate when reacted with an aqueous solution of ferrous sulfate (FeSO₄), we will analyze the reactions of FeSO₄ with each of the given options: sodium hydroxide (NaOH), ammonia solution (NH₄OH), and sodium carbonate (Na₂CO₃).

### Step-by-Step Solution:

1. **Identify the Compounds:**
- We have three compounds to consider: sodium hydroxide (NaOH), ammonia solution (NH₄OH), and sodium carbonate (Na₂CO₃).

2. **Reaction with Sodium Hydroxide (NaOH):**
- When FeSO₄ reacts with NaOH, the reaction can be written as:
\[ \text{FeSO}_4 + 2 \text{NaOH} \rightarrow \text{Fe(OH)}_2 \downarrow + \text{Na}_2\text{SO}_4 \]
- Here, Fe(OH)₂ is a green precipitate. Therefore, FeSO₄ produces a precipitate with NaOH.

3. **Reaction with Ammonia Solution (NH₄OH):**
- The reaction of FeSO₄ with ammonia solution can be represented as:
\[ \text{FeSO}_4 + 2 \text{NH}_4\text{OH} \rightarrow \text{Fe(OH)}_2 \downarrow + \text{(NH}_4)_2\text{SO}_4 \]
- Again, Fe(OH)₂ is formed as a green precipitate. Thus, FeSO₄ produces a precipitate with ammonia solution.

4. **Reaction with Sodium Carbonate (Na₂CO₃):**
- The reaction of FeSO₄ with sodium carbonate is:
\[ \text{FeSO}_4 + \text{Na}_2\text{CO}_3 \rightarrow \text{FeCO}_3 \downarrow + \text{Na}_2\text{SO}_4 \]
- Here, FeCO₃ is also a solid precipitate. Hence, FeSO₄ produces a precipitate with sodium carbonate.

5. **Conclusion:**
- Since FeSO₄ produces a precipitate with sodium hydroxide, ammonia solution, and sodium carbonate, we can conclude that it does not produce a precipitate with "none of these" (option 4). Therefore, the correct answer is **none of these**.

### Final Answer:
**None of these (Option 4)**
