Which of the following gives a precipitate with `Pb(NO_(3))_(2)`?

Options

A. Sodium chloride
B. Sodium acetate
C. Sodium nitrate
D. Disodium hydrogen phosphate

Explanation

To determine which of the given compounds gives a precipitate with lead nitrate (Pb(NO₃)₂), we will analyze each compound one by one.

### Step-by-step Solution:

1. **Identify the Compounds**:
The compounds we need to analyze are:
- Sodium Chloride (NaCl)
- Sodium Acetate (NaCH₃COO)
- Sodium Nitrate (NaNO₃)
- Di-sodium Hydrogen Phosphate (Na₂HPO₄)

2. **Reaction with Lead Nitrate**:
We will check each compound to see if it reacts with lead nitrate to form a precipitate.

3. **Sodium Chloride (NaCl)**:
- Reaction:
\[ \text{NaCl} + \text{Pb(NO}_3\text{)}_2 \rightarrow \text{NaNO}_3 + \text{PbCl}_2 \]
- Result: Lead(II) chloride (PbCl₂) is formed, which is a white precipitate.

4. **Sodium Acetate (NaCH₃COO)**:
- Reaction:
\[ \text{NaCH}_3\text{COO} + \text{Pb(NO}_3\text{)}_2 \rightarrow \text{No precipitate} \]
- Result: No precipitate forms because sodium acetate does not produce a precipitate with lead nitrate.

5. **Sodium Nitrate (NaNO₃)**:
- Reaction:
\[ \text{NaNO}_3 + \text{Pb(NO}_3\text{)}_2 \rightarrow \text{No precipitate} \]
- Result: No precipitate forms as both are soluble nitrates.

6. **Di-sodium Hydrogen Phosphate (Na₂HPO₄)**:
- Reaction:
\[ \text{Na}_2\text{HPO}_4 + \text{Pb(NO}_3\text{)}_2 \rightarrow \text{No precipitate} \]
- Result: No precipitate forms with lead nitrate.

### Conclusion:
The only compound that gives a precipitate with lead nitrate is **Sodium Chloride (NaCl)**, which forms lead(II) chloride (PbCl₂) as a white precipitate.

### Final Answer:
**Sodium Chloride (NaCl)** gives a precipitate with Pb(NO₃)₂.
