Options

A. Acidic
B. Basic
C. Neutral
D. Amphoteric

Explanation

To determine the nature of the aqueous solution of CuSO₄ (Copper Sulfate), we can analyze the ions produced when it dissolves in water.

### Step-by-Step Solution:

1. **Dissociation of CuSO₄ in Water**:
When Copper Sulfate (CuSO₄) is dissolved in water, it dissociates into its constituent ions:
\[ \text{CuSO}_4 \rightarrow \text{Cu}^{2+} + \text{SO}_4^{2-} \]

2. **Nature of Cu²⁺ Ion**:
The Copper ion (Cu²⁺) is a cation that can exhibit acidic behavior. It is derived from a weak base (Cu(OH)₂) and can hydrolyze in water to form a weak acidic solution:
\[ \text{Cu}^{2+} + \text{H}_2\text{O} \rightleftharpoons \text{Cu(OH)}^+ + \text{H}^+ \]
This reaction shows that Cu²⁺ can release H⁺ ions, contributing to the acidity of the solution.

3. **Nature of SO₄²⁻ Ion**:
The sulfate ion (SO₄²⁻) is derived from sulfuric acid (H₂SO₄), which is a strong acid. Therefore, the sulfate ion does not contribute to the basicity of the solution.

4. **Overall Nature of the Solution**:
Since the Cu²⁺ ion contributes to the acidity of the solution and the sulfate ion does not contribute to basicity, the overall nature of the aqueous solution of CuSO₄ is acidic.

5. **Conclusion**:
Thus, the aqueous solution of CuSO₄ is acidic.

### Final Answer:
The aqueous solution of CuSO₄ is acidic.
