Which of the following salt does not give any ppt with `AgNO_(3)` sol. :

Options

A. `F^(-)` salt
B. `Cl^(-)` salt
C. `Br^(-)` salt
D. `I^(-)` salt

Explanation

To determine which salt does not give any precipitate with AgNO₃ solution, we need to analyze the behavior of different halide salts when they react with silver nitrate (AgNO₃).

### Step-by-Step Solution:

1. **Understanding the Reaction**: When a salt containing a halide ion (F⁻, Cl⁻, Br⁻, I⁻) is added to AgNO₃, a reaction occurs that can lead to the formation of a precipitate. The general reaction can be represented as:
\[ \text{Salt} + \text{AgNO}_3 \rightarrow \text{AgX} + \text{NaNO}_3 \]
where X is the halide ion.

2. **Identifying the Halides**: The common halides that we consider are:
- Fluoride (F⁻)
- Chloride (Cl⁻)
- Bromide (Br⁻)
- Iodide (I⁻)

3. **Analyzing Each Halide**:
- **Fluoride (F⁻)**: When F⁻ reacts with AgNO₃, it forms AgF. AgF is soluble in water, meaning it does not form a precipitate.
- **Chloride (Cl⁻)**: When Cl⁻ reacts with AgNO₃, it forms AgCl, which is insoluble in water and forms a white precipitate.
- **Bromide (Br⁻)**: When Br⁻ reacts with AgNO₃, it forms AgBr, which is also insoluble in water and forms a pale yellow precipitate.
- **Iodide (I⁻)**: When I⁻ reacts with AgNO₃, it forms AgI, which is insoluble in water and forms a yellow precipitate.

4. **Conclusion**: Among the halides, only AgF does not form a precipitate with AgNO₃ because it is soluble in water. Therefore, the salt that does not give any precipitate with AgNO₃ is the one containing fluoride ions (F⁻).

### Final Answer:
The salt that does not give any precipitate with AgNO₃ is the one containing **F⁻ (Fluoride)**.
