Aqueous solution of `SO_(2)` is :

Options

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

Explanation

To determine the nature of an aqueous solution of SO₂ (sulfur dioxide), we can follow these steps:

### Step-by-Step Solution:

1. **Understanding SO₂ in Water**:
- When sulfur dioxide (SO₂) is dissolved in water, it reacts with water to form sulfurous acid (H₂SO₃).

2. **Chemical Reaction**:
- The reaction can be represented as:
\[ SO_2 (g) + H_2O (l) \rightarrow H_2SO_3 (aq) \]

3. **Dissociation of Sulfurous Acid**:
- Sulfurous acid (H₂SO₃) can further dissociate in water:
\[ H_2SO_3 (aq) \rightleftharpoons 2H^+ (aq) + SO_3^{2-} (aq) \]

4. **Acidic Nature**:
- The dissociation produces hydrogen ions (H⁺), which indicates that the solution is acidic. The presence of H⁺ ions is a characteristic of acidic solutions.

5. **Conclusion**:
- Therefore, the aqueous solution of SO₂ is acidic due to the formation of sulfurous acid and the release of hydrogen ions.

### Final Answer:
The aqueous solution of SO₂ is **acidic**.
