An aqueous solution of salt gives salt precipitate with `AgNO_(3)` solution as well as with dilute `H_(2)SO_(4)`. It may be

Options

A. `Pb(NO_(3))_(2)`
B. `Ba(NO_(3))_(2)`
C. `BaCl_(2)`
D. `CuCl_(2)`

Explanation

To solve the question regarding the aqueous solution of salt that gives a precipitate with both AgNO₃ and dilute H₂SO₄, we will follow these steps:

### Step 1: Identify the salts that react with AgNO₃
AgNO₃ (silver nitrate) is known to react with halides (like Cl⁻, Br⁻, I⁻) and some other anions to form precipitates. Common precipitates include:
- AgCl (white)
- AgBr (cream)
- AgI (yellow)

### Step 2: Identify the salts that react with dilute H₂SO₄
Dilute H₂SO₄ (sulfuric acid) can react with certain salts to form precipitates. A notable reaction is with barium salts, which forms barium sulfate (BaSO₄), a white precipitate.

### Step 3: Analyze the given information
The question states that the salt gives precipitates with both AgNO₃ and dilute H₂SO₄. This means the salt must contain an anion that can form a precipitate with both reagents.

### Step 4: Consider possible salts
- **Barium Chloride (BaCl₂)**:
- When BaCl₂ reacts with AgNO₃, it forms AgCl (white precipitate) and Ba(NO₃)₂.
- When BaCl₂ reacts with dilute H₂SO₄, it forms BaSO₄ (white precipitate) and HCl.

Thus, BaCl₂ meets the criteria of forming precipitates with both AgNO₃ and dilute H₂SO₄.

### Conclusion
The salt that gives a precipitate with both AgNO₃ and dilute H₂SO₄ is **Barium Chloride (BaCl₂)**.
