Which of the following act as a stabiliser for the storage of `H_(2)O_(2)`?

Options

A. Alkali
B. Dust
C. Urea
D. None of these.

Explanation

To determine which of the following acts as a stabilizer for the storage of hydrogen peroxide (H₂O₂), we need to analyze the options provided and understand the properties of H₂O₂.

### Step-by-Step Solution:

1. **Understanding Hydrogen Peroxide (H₂O₂)**:
- H₂O₂ is a powerful oxidizing agent that is known to decompose easily into water (H₂O) and oxygen gas (O₂). This decomposition can be accelerated by various factors, including light, heat, and impurities.

2. **Identifying the Problem**:
- The question asks for a substance that can stabilize H₂O₂ during storage, preventing or slowing down its decomposition.

3. **Evaluating the Options**:
- **Alkali**: While alkalis can catalyze the decomposition of H₂O₂, they do not stabilize it. Therefore, alkali is not a suitable answer.
- **Dust**: The presence of dust can also lead to explosive decomposition of H₂O₂. Thus, dust cannot be considered a stabilizer.
- **Urea**: Urea is known to act as a stabilizer for H₂O₂. When added in small amounts, it can help inhibit the decomposition process, making it a suitable choice for stabilization.

4. **Conclusion**:
- Based on the analysis, the correct answer is **Urea**. It acts as a stabilizer for the storage of hydrogen peroxide.

### Final Answer:
**Urea acts as a stabilizer for the storage of H₂O₂.**
