An aqueous solution of `KNO_3` is basic due to hydrolysis

Answer

To determine whether the statement "An aqueous solution of KNO3 is basic due to hydrolysis" is true or false, we need to analyze the components of potassium nitrate (KNO3) and their behavior in solution.

### Step-by-Step Solution:

1. **Identify the Components of KNO3**:
- KNO3 is composed of potassium ions (K⁺) and nitrate ions (NO3⁻).
- Potassium nitrate is formed from potassium hydroxide (KOH), which is a strong base, and nitric acid (HNO3), which is a strong acid.

2. **Determine the Nature of the Parent Acid and Base**:
- KOH is a strong base, and it completely dissociates in water to produce K⁺ and OH⁻ ions.
- HNO3 is a strong acid, and it completely dissociates in water to produce H⁺ and NO3⁻ ions.

3. **Analyze the Hydrolysis of KNO3**:
- A salt formed from a strong acid and a strong base (like KNO3) does not undergo hydrolysis.
- Hydrolysis occurs when a salt is formed from a weak acid or weak base, leading to the formation of H⁺ or OH⁻ ions in solution, which can alter the pH.

4. **Conclusion on the pH of KNO3 Solution**:
- Since KNO3 is derived from a strong acid and a strong base, the solution of KNO3 in water will be neutral, with a pH around 7.
- Therefore, the statement that an aqueous solution of KNO3 is basic due to hydrolysis is false.

### Final Answer:
The statement is **false**. An aqueous solution of KNO3 is neutral and does not exhibit basic properties due to hydrolysis.
