Assertion: Copper sulphate solution can be kept in a zinc vessel.
Reason: The position of copper is higher than zinc is the electrochemical series.

Options

A. If both assertion and reason are true, and reason is the true explanation of the assertion
B. if both assertion and reason are true, but reason is not the true explanation of the assertion.
C. if assertion is true, but reason is false.
D. If both assertion and reason are false.

Explanation

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

### Step 1: Understand the Assertion
The assertion states that "Copper sulphate solution can be kept in a zinc vessel." This implies that zinc is compatible with copper sulphate and will not react adversely when in contact with it.

### Step 2: Analyze the Reactivity of Zinc and Copper
Next, we need to consider the reactivity of zinc and copper. In the electrochemical series (or reactivity series), metals are arranged based on their reactivity. Zinc is more reactive than copper. This means that zinc can displace copper from its compounds.

### Step 3: Reaction Between Zinc and Copper Sulphate
When zinc is placed in a copper sulphate solution, a displacement reaction occurs:
\[ \text{Zn} + \text{CuSO}_4 \rightarrow \text{ZnSO}_4 + \text{Cu} \]
Here, zinc displaces copper from copper sulphate, forming zinc sulphate and solid copper.

### Step 4: Conclusion on the Assertion
Since zinc can react with copper sulphate and displace copper, it indicates that keeping copper sulphate solution in a zinc vessel is not advisable as it will lead to a reaction. Therefore, the assertion is **incorrect**.

### Step 5: Analyze the Reason
The reason states that "The position of copper is higher than zinc in the electrochemical series." This is also incorrect because, in the electrochemical series, zinc is placed above copper, indicating that zinc is more reactive than copper.

### Final Conclusion
- **Assertion**: Incorrect (Copper sulphate solution cannot be kept in a zinc vessel as it will react).
- **Reason**: Incorrect (Copper is not higher than zinc in the electrochemical series; zinc is higher).

### Summary
Both the assertion and the reason are incorrect.
