Chlorine gas is liberated at the anode. This gas can be easily identified as it has a distinctive smell similar to that of __________.

Options

A. Salt
B. Fruity smell
C. Woody smell
D. Bleaching power

Answer

To solve the question, we need to identify the distinctive smell of chlorine gas that is liberated at the anode during electrolysis.

### Step-by-Step Solution:

1. **Understanding Chlorine Gas**: Chlorine gas (Cl2) is a chemical compound that is often released during the electrolysis of saltwater or other chlorine-containing solutions.

2. **Identifying the Smell**: The question asks for a comparison of the smell of chlorine gas. We need to think about common substances that have a smell similar to chlorine.

3. **Considering Options**: The options provided are:
- Salt
- Fruity smell
- Woody smell
- Bleaching powder

4. **Analyzing Each Option**:
- **Salt**: Does not have a distinctive smell similar to chlorine.
- **Fruity smell**: This is not associated with chlorine.
- **Woody smell**: Again, not related to chlorine.
- **Bleaching powder**: This is known to have a strong smell that is similar to chlorine because it contains chlorine in its chemical structure.

5. **Conclusion**: Based on the analysis, the gas that has a distinctive smell similar to chlorine is **bleaching powder**.

### Final Answer:
Chlorine gas is liberated at the anode. This gas can be easily identified as it has a distinctive smell similar to **bleaching powder**.
