Assertion: Nitric acid and water form maximum boiling azeotrope.
Reason: Azeotropes are binary mixtureshaving the same composition in liquid and vapour phase.

Options

A. Assertion and reason both are correct statements and reason is correct explanation for assertion.
B. Assertion and reason both are correct statements but reason is not correct explanation for assertion.
C. Assertion is correct statement but reason is wrong statement.
D. Assertion is wrong statement but reason is correct statement.

Answer

To analyze the given assertion and reason, we will break down the statements step by step.

### Step 1: Understand the Assertion
The assertion states that "Nitric acid and water form a maximum boiling azeotrope."

**Explanation:**
Azeotropes are mixtures of two or more liquids that boil at a constant temperature and maintain the same composition in both the liquid and vapor phases. A maximum boiling azeotrope occurs when the boiling point of the mixture is higher than that of either of the pure components.

### Step 2: Understand the Reason
The reason states that "Azeotropes are binary mixtures having the same composition in liquid and vapor phase."

**Explanation:**
This statement is true. In an azeotropic mixture, the composition of the liquid phase and the vapor phase remains constant during boiling. This means that when the mixture is boiled, it will produce vapor that has the same composition as the liquid.

### Step 3: Analyze the Relationship Between Assertion and Reason
Now, we need to determine if the reason provided supports the assertion.

**Analysis:**
The assertion is correct because nitric acid (HNO3) and water do indeed form a maximum boiling azeotrope. The reason is also correct as it accurately describes what an azeotrope is. However, the reason does not specifically explain why nitric acid and water form a maximum boiling azeotrope.

### Conclusion
Both the assertion and the reason are true, but the reason does not adequately explain the assertion. Therefore, the correct conclusion is that the assertion is true, the reason is true, but the reason does not support the assertion.

### Final Answer
- **Assertion:** True
- **Reason:** True
- **Conclusion:** The reason does not explain the assertion.
