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 \( H_2O_2 \) (hydrogen peroxide), we will analyze its properties and how it functions as a bleaching agent.

### Step-by-Step Solution:

1. **Understanding Bleaching Agents**:
Bleaching agents are substances that can remove color from materials. They typically work by breaking down colored compounds into colorless ones.

**Hint**: Consider what properties make a substance effective at breaking down color.

2. **Properties of \( H_2O_2 \)**:
Hydrogen peroxide is known for its oxidizing properties. It can release nascent oxygen, which is a highly reactive form of oxygen.

**Hint**: Recall the definition of an oxidizing agent and how it interacts with other substances.

3. **Chemical Reaction**:
The bleaching action of \( H_2O_2 \) can be represented by the following reaction:
\[ H_2O_2 \rightarrow H_2O + \text{nascent oxygen} \]
The nascent oxygen produced is what contributes to the bleaching effect.

**Hint**: Think about how the release of nascent oxygen can affect the bonds in colored compounds.

4. **Mechanism of Bleaching**:
The nascent oxygen reacts with the chromophores (the part of the molecule responsible for its color) in colored substances. This reaction breaks the bonds in the chromophores, effectively decolorizing the material.

**Hint**: Consider how breaking chemical bonds can lead to a loss of color.

5. **Conclusion**:
Therefore, the bleaching action of \( H_2O_2 \) is primarily due to its ability to act as an oxidizing agent through the release of nascent oxygen, which reacts with and breaks down colored compounds.

**Final Answer**: The bleaching action of \( H_2O_2 \) is due to its oxidizing nature and the release of nascent oxygen.

### Summary of the Answer:
The bleaching action of \( H_2O_2 \) is due to its property as an oxidizing agent, which releases nascent oxygen that reacts with colored substances to break their bonds and remove color.
