Assertion : The aqueous solution of `CuSO_4` is acidic in nature.
Reason : Copper sulphate is a salt of a weak base and a strong acid.

Options

A. If both Assertion and Reason are CORRECT and Reason is the CORRECT explanations of the Assertion
B. If both Assertion and Reason are CORRECT but Reaon is not CORRECT explanation of the Assertion.
C. If Assertion is CORRECT but Reasson is INCORRECT.
D. If Assertion is INCORRECT but Reason is CORRECT.

Answer

To solve the assertion and reasoning question regarding the nature of the aqueous solution of CuSO4, we will follow these steps:

### Step 1: Understand the Assertion
The assertion states that the aqueous solution of CuSO4 is acidic in nature. We need to determine if this statement is true.

### Step 2: Analyze the Composition of CuSO4
Copper sulfate (CuSO4) is a salt formed from the reaction of a weak base (copper hydroxide, Cu(OH)2) and a strong acid (sulfuric acid, H2SO4).

### Step 3: Conduct Salt Hydrolysis
When CuSO4 is dissolved in water, it undergoes hydrolysis. The dissociation can be represented as:
\[ \text{CuSO}_4 \rightarrow \text{Cu}^{2+} + \text{SO}_4^{2-} \]

### Step 4: Determine the Nature of the Ions
- The sulfate ion (SO4^2-) comes from a strong acid (H2SO4) and does not significantly affect the pH of the solution.
- The copper ion (Cu^2+) comes from a weak base (Cu(OH)2) and can hydrolyze to produce H+ ions, which contributes to the acidity of the solution.

### Step 5: Conclude the Nature of the Solution
Since the Cu^2+ ion can release H+ ions upon hydrolysis, the overall effect is that the solution becomes acidic. Therefore, the assertion is correct.

### Step 6: Analyze the Reason
The reason states that copper sulfate is a salt of a weak base and a strong acid. This is true, as we have established that CuSO4 is derived from the weak base Cu(OH)2 and the strong acid H2SO4.

### Step 7: Determine the Relationship Between Assertion and Reason
Both the assertion and the reason are correct, and the reason provides a correct explanation for the assertion.

### Final Conclusion
Both the assertion and the reason are correct, and the reason is a correct explanation of the assertion.

### Answer
The correct option is: Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
