Answer

To analyze the statements provided in the question, we will break down the information regarding hypochlorous acid (HClO) and sodium hypochlorite.

### Step-by-Step Solution:

1. **Understanding Hypochlorous Acid (HClO)**:
- Hypochlorous acid is known to be a powerful oxidizing agent. This means it has the ability to gain electrons from other substances, thereby oxidizing them.
- It is also recognized as a bleaching agent due to its ability to remove color from substances.

**Hint**: Recall the properties of oxidizing agents and how they interact with other substances.

2. **Examining Sodium Hypochlorite**:
- Sodium hypochlorite (NaClO) is a compound that can dissociate in solution to produce hypochlorous acid (HClO) and sodium ions (Na+).
- In aqueous solution, sodium hypochlorite can undergo a disproportionation reaction, where it can oxidize some of its hypochlorite ions (ClO-) to chlorine gas (Cl2) while reducing others to chloride ions (Cl-).

**Hint**: Disproportionation reactions involve a single substance being both oxidized and reduced simultaneously.

3. **Evaluating Statement 1**:
- Statement 1 claims that HClO acts as a powerful oxidizing and bleaching agent. This statement is true based on the known properties of hypochlorous acid.

**Hint**: Consider the definitions of oxidizing and bleaching agents and how they relate to HClO.

4. **Evaluating Statement 2**:
- Statement 2 asserts that sodium hypochlorite in solution undergoes a disproportionation reaction. This statement is also true, as sodium hypochlorite does indeed undergo such reactions in solution.

**Hint**: Think about the chemical behavior of hypochlorite ions in solution and the products formed during disproportionation.

5. **Conclusion**:
- Both statements are true. However, the second statement does not provide a justification for the first statement. The disproportionation of sodium hypochlorite does not explain why HClO is a powerful oxidizing and bleaching agent; it merely describes a reaction involving sodium hypochlorite.

**Final Answer**: Both statements are true, but Statement 2 is not the correct explanation for Statement 1. Therefore, the answer is option B.

### Summary:
- **Statement 1**: True (HClO is a powerful oxidizing and bleaching agent).
- **Statement 2**: True (NaClO undergoes disproportionation).
- **Conclusion**: Both statements are true, but Statement 2 does not explain Statement 1.
