C. for clear/colourless solution
D. For white ppt.

Answer

To determine the outcome of the reaction between KMnO₄ (potassium permanganate) and NaNO₃ (sodium nitrate), we can analyze the properties of the reactants and the conditions under which they react.

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The first reactant is KMnO₄, which is known for its deep purple color due to the presence of MnO₄⁻ ions.
- The second reactant is NaNO₃, which is a colorless, soluble salt.

2. **Consider the Nature of the Reaction**:
- KMnO₄ is a strong oxidizing agent, while NaNO₃ is a stable salt that does not typically participate in redox reactions under normal conditions.
- There is no indication that a reaction will occur between these two compounds, as neither compound can oxidize or reduce the other.

3. **Look for Signs of Reaction**:
- A typical sign of a chemical reaction includes the formation of a precipitate, gas, or a color change. In this case, we see no signs of any of these.
- Since there is no downward arrow (indicating precipitate formation) or any other indication of a reaction, we conclude that no reaction occurs.

4. **Analyze the Options**:
- Option 1: Color precipitate forms - Incorrect, as no precipitate is formed.
- Option 2: Color solution forms - This is possible since KMnO₄ remains purple in solution.
- Option 3: Clear and colorless solution forms - Incorrect, as KMnO₄ does not lose its color.
- Option 4: White precipitate forms - Incorrect, as no precipitate is formed.

5. **Conclusion**:
- The correct answer is that the reaction results in a colored solution (purple) due to the presence of KMnO₄, and thus, the correct option is Option 2.

### Final Answer:
No reaction occurs between KMnO₄ and NaNO₃, but the solution remains purple due to the KMnO₄.
