Options

B. Statement-1 is True, Statement-2, is True, Statement-2 is NOT a correct explanation for Statement-6
C. Statement-1 is True, Statement-2 is False
D. Statement-1 is False, Statement-2 is True

Answer

To analyze the statements provided, we will break down the reasoning behind each statement step by step.

### Step 1: Understanding Statement 1
**Statement 1**: Moistened ammonium salts give the smell of NH₃.

- Ammonium salts, such as ammonium chloride (NH₄Cl), can release ammonia (NH₃) when they are moistened.
- When ammonium salts are rubbed or heated, they can dissociate into ammonia gas and an acid (like HCl in the case of NH₄Cl).
- The smell of ammonia is noticeable because NH₃ is a volatile compound that can easily evaporate into the air.

**Conclusion for Statement 1**: This statement is true because the dissociation of moistened ammonium salts produces ammonia, which has a characteristic smell.

### Step 2: Understanding Statement 2
**Statement 2**: Ammonium salts give NH₃ on heating with concentrated NaOH.

- When ammonium salts are heated with concentrated sodium hydroxide (NaOH), a chemical reaction occurs.
- For example, when ammonium chloride (NH₄Cl) is heated with NaOH, the reaction can be represented as:
\[ NH₄Cl + NaOH \rightarrow NH₃ + NaCl + H₂O \]
- This reaction shows that ammonia is indeed produced when ammonium salts react with concentrated NaOH.

**Conclusion for Statement 2**: This statement is also true because heating ammonium salts with concentrated NaOH results in the formation of ammonia gas.

### Step 3: Relationship Between the Statements
- Both statements are true independently. However, they do not directly explain each other.
- Statement 1 describes the smell of ammonia from moistened ammonium salts, while Statement 2 describes the production of ammonia when ammonium salts are heated with NaOH.

### Final Conclusion
- Both statements are true, but Statement 2 does not serve as a correct explanation for Statement 1. Therefore, the correct answer is that both statements are true, but Statement 2 is not the correct explanation for Statement 1.
