Assertion (A): Copper sulphate can be stored in zinc vessel.
Reason (R): Zinc is more reactive than copper.

Options

A. Both A and R are true but R is NOT the correct explanation of A
B. Both A and R are true but R is NOT the correct explanation of A
C. A is true but R is false
D. A is false and R is True

Explanation

To solve the assertion-reason question, we need to analyze both the assertion (A) and the reason (R) provided.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that "Copper sulphate can be stored in zinc vessel."
- We need to evaluate whether this statement is true or false.

2. **Understanding the Reason (R)**:
- The reason states that "Zinc is more reactive than copper."
- This statement is true according to the reactivity series of metals, where zinc is indeed more reactive than copper.

3. **Analyzing the Implications**:
- If zinc is more reactive than copper, it means that zinc can displace copper from its compounds.
- Therefore, if we store copper sulphate (CuSO₄) in a zinc vessel, the zinc will react with the copper ions in the copper sulphate solution.

4. **Chemical Reaction**:
- The reaction that occurs is:
\[ \text{Zn} + \text{CuSO}_4 \rightarrow \text{ZnSO}_4 + \text{Cu} \]
- In this reaction, zinc displaces copper from copper sulphate, forming zinc sulphate (ZnSO₄) and releasing copper.

5. **Conclusion about the Assertion**:
- Since zinc displaces copper from copper sulphate, the assertion that copper sulphate can be stored in a zinc vessel is **incorrect**.
- Therefore, the assertion (A) is false.

6. **Conclusion about the Reason**:
- The reason (R) is true because zinc is indeed more reactive than copper.

7. **Final Evaluation**:
- The assertion (A) is false, and the reason (R) is true.
- Thus, the correct answer to the assertion-reason question is that the assertion is incorrect while the reason is correct.

### Final Answer:
- Assertion (A) is false.
- Reason (R) is true.
- Therefore, the answer is: Assertion is incorrect and Reason is correct.
