D. For white ppt.

Answer

To solve the question regarding the reaction between AgNO3 (silver nitrate) and NaF (sodium fluoride), we will analyze the situation step by step.

### Step-by-Step Solution:

1. **Identify the Reactants**:
The reactants in this case are AgNO3 (silver nitrate) and NaF (sodium fluoride). Both are soluble in water.

2. **Write the Chemical Equation**:
When AgNO3 and NaF are mixed in solution, the expected reaction can be written as:
\[ \text{AgNO}_3(aq) + \text{NaF}(aq) \rightarrow \text{AgF}(s) + \text{NaNO}_3(aq) \]
However, we need to check if AgF (silver fluoride) is soluble or if a precipitate forms.

3. **Check Solubility of Products**:
- AgF is known to be sparingly soluble in water, but it does not form a precipitate under normal conditions.
- NaNO3 is soluble in water.

4. **Determine if a Reaction Occurs**:
Since AgF does not precipitate out of solution and remains dissolved, we conclude that there is no observable reaction.

5. **Analyze the Options**:
- Option 1: Colored precipitate formed - Incorrect (no precipitate)
- Option 2: Colored solution formed - Incorrect (both reactants are colorless)
- Option 3: Clear and colorless solution formed - Correct (both reactants are colorless)
- Option 4: White precipitate formed - Incorrect (no precipitate)

6. **Conclusion**:
The correct answer is that a clear and colorless solution is formed, indicating that there is no reaction between AgNO3 and NaF.

### Final Answer:
The reaction between AgNO3 and NaF results in a clear and colorless solution, indicating that no reaction occurs.
