Bleaching action of `H_(2)O_(2)` is due to its :

Options

A. oxidising nature
B. reducing nature
C. acidic nature
D. thermal instability

Answer

To solve the question regarding the bleaching action of \( H_2O_2 \), we will break down the explanation into clear steps.

### Step-by-Step Solution:

1. **Understanding the Composition of \( H_2O_2 \)**:
- Hydrogen peroxide (\( H_2O_2 \)) is a chemical compound that consists of two hydrogen atoms and two oxygen atoms. It can decompose into water (\( H_2O \)) and nascent oxygen (\( O \)).

2. **Decomposition of \( H_2O_2 \)**:
- When \( H_2O_2 \) is added to a solution, it can dissociate or decompose to produce nascent oxygen. This nascent oxygen is highly reactive and plays a crucial role in the bleaching process.

3. **Role of Nascent Oxygen**:
- The nascent oxygen produced from the decomposition of \( H_2O_2 \) acts as an oxidizing agent. It interacts with colored substances, specifically chromophores, which are responsible for the color in materials like fabrics.

4. **Oxidation of Chromophores**:
- Chromophores are parts of molecules that absorb visible light and give color to substances. When nascent oxygen oxidizes these chromophores, it alters their structure, preventing them from absorbing light in the same way. As a result, the color disappears.

5. **Resulting Effect**:
- The oxidation of chromophores leads to a loss of color, causing the material to appear white or colorless. This is the bleaching action of \( H_2O_2 \).

6. **Identifying the Correct Option**:
- The question asks for the reason behind the bleaching action of \( H_2O_2 \). The options provided include:
1. Oxidizing nature
2. Reducing nature
3. Acidic nature
4. Thermal instability
- Since the bleaching action is primarily due to the oxidizing nature of nascent oxygen, the correct answer is the first option: **Oxidizing nature**.

### Final Answer:
The bleaching action of \( H_2O_2 \) is due to its **oxidizing nature**.
