D. Amphoteric

Answer

To determine the nature of the aqueous solution of copper(II) sulfate (CuSO₄), we can follow these steps:

### Step 1: Understand the Dissolution of CuSO₄
When copper(II) sulfate is dissolved in water, it dissociates into its ions:
\[ \text{CuSO}_4 (s) \rightarrow \text{Cu}^{2+} (aq) + \text{SO}_4^{2-} (aq) \]

### Step 2: Analyze the Ions in Solution
The ions produced are:
- Copper ions (\(\text{Cu}^{2+}\))
- Sulfate ions (\(\text{SO}_4^{2-}\))

### Step 3: Determine the Nature of the Ions
- The copper ion (\(\text{Cu}^{2+}\)) is known to hydrolyze in water, which means it can react with water to form a weak acid:
\[ \text{Cu}^{2+} + 2 \text{H}_2\text{O} \rightleftharpoons \text{Cu(OH)}_2 + 2 \text{H}^+ \]

- The sulfate ion (\(\text{SO}_4^{2-}\)) is the conjugate base of a strong acid (sulfuric acid, H₂SO₄) and does not significantly affect the pH of the solution.

### Step 4: Conclusion on the Nature of the Solution
Since the copper ion produces hydrogen ions (\(\text{H}^+\)) upon hydrolysis, it results in an increase in the acidity of the solution. Therefore, the aqueous solution of CuSO₄ is acidic in nature.

### Final Answer
The nature of the aqueous solution of CuSO₄ is **acidic**.
