An aqueous solution of `H_(2)O_(2)`

Options

A. Alkaline
B. Neutral
C. Strongly acidic
D. weekly acidic.

Explanation

To determine the nature of an aqueous solution of hydrogen peroxide (H₂O₂), we can follow these steps:

### Step 1: Understand the Dissociation of H₂O₂
When hydrogen peroxide (H₂O₂) is dissolved in water, it can dissociate into hydronium ions (H₃O⁺) and the peroxide ion (HO₂⁻):
\[ H₂O₂ + H₂O \rightarrow H₃O^+ + HO₂^- \]

### Step 2: Analyze the Products
The dissociation produces H₃O⁺, which is known to be a hydronium ion. The presence of H₃O⁺ indicates that the solution will have acidic properties.

### Step 3: Identify the Nature of the Solution
Since H₃O⁺ is produced, we can conclude that the solution is acidic. However, H₂O₂ is considered a weak acid, meaning it does not completely dissociate in solution.

### Step 4: Confirm the Weak Acidity
To confirm that H₂O₂ is a weak acid, we can compare it with strong acids. Strong acids completely dissociate in water, while weak acids only partially dissociate. Therefore, the aqueous solution of H₂O₂ is weakly acidic.

### Conclusion
Based on the above analysis, we can conclude that an aqueous solution of H₂O₂ is weakly acidic in nature. Thus, the correct option is D.
