Assertion : A solution of table salt in a glass of water is homogeneous
Reason : A solution having same composition throughout is heterogeneous

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion.
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion.
C. If Assertion is true statement but Reason is false.
D. If both Assertion and Reason are false statements.

Answer

To solve the question, we need to analyze both the assertion and the reason provided.

### Step 1: Understand the Assertion
The assertion states: "A solution of table salt in a glass of water is homogeneous."

- A homogeneous solution is one where the composition is uniform throughout. When table salt (sodium chloride, NaCl) is dissolved in water, it forms a uniform mixture. This means that the salt is evenly distributed throughout the water, and you cannot distinguish between the salt and the water visually.

**Conclusion**: The assertion is correct.

### Step 2: Understand the Reason
The reason states: "A solution having the same composition throughout is heterogeneous."

- This statement is incorrect. A solution that has the same composition throughout is classified as homogeneous, not heterogeneous. Heterogeneous mixtures have different compositions in different parts of the mixture, meaning you can see distinct phases or components.

**Conclusion**: The reason is false.

### Final Conclusion
- The assertion is true, and the reason is false. Therefore, the correct option is that the assertion is true and the reason is false.

### Summary of the Solution
1. The assertion is correct: A solution of table salt in a glass of water is homogeneous.
2. The reason is incorrect: A solution having the same composition throughout is homogeneous, not heterogeneous.
3. Therefore, the correct answer is that the assertion is true and the reason is false.
