Which has bleaching action due to reducing property and it is temporary?

Options

A. `H_(2) O_(2)`
B. `O_(3)`
C. `SO_(2)`
D. `Cl_(2)`

Answer

To solve the question "Which has bleaching action due to reducing property and it is temporary?", we can follow these steps:

### Step 1: Understand Bleaching Agents
Bleaching agents are substances that remove color from materials, such as textiles or clothes. They can act through different mechanisms, primarily oxidation or reduction.

**Hint:** Remember that bleaching can occur through both oxidizing and reducing agents, but the question specifically asks for a reducing agent.

### Step 2: Identify the Nature of the Agents
The question provides several options, and we need to determine which of these has a reducing property. Common bleaching agents include:
- SO2 (sulfur dioxide)
- H2O2 (hydrogen peroxide)
- O3 (ozone)
- Cl2 (chlorine)

**Hint:** Recall the properties of each agent: SO2 is known for its reducing properties, while H2O2, O3, and Cl2 are primarily oxidizing agents.

### Step 3: Analyze the Reducing Property of SO2
SO2 acts as a reducing agent. When it interacts with colored substances, it can reduce them, effectively removing their color. This process is temporary because once SO2 is exposed to oxygen in the atmosphere, it can be reoxidized back to its original state, restoring the color.

**Hint:** Consider the chemical reactions involved in bleaching. Reducing agents donate electrons, which can lead to the decolorization of substances.

### Step 4: Conclusion
Based on the analysis, SO2 is the correct answer as it has bleaching action due to its reducing property, and this action is temporary.

**Final Answer:** The bleaching agent that has bleaching action due to reducing property and is temporary is **SO2 (sulfur dioxide)**.
