Give suitable reason(s) for each of the following:
Calcium chloride is not used to dry ammonia.

Explanation

### Step-by-Step Solution:

1. **Understanding the Role of Calcium Chloride**: Calcium chloride (CaCl₂) is commonly used as a drying agent due to its hygroscopic nature, meaning it can absorb moisture from the air.

2. **Identifying the Problem with Ammonia**: Ammonia (NH₃) is a gas that can react with certain substances. When considering drying agents, it is crucial to ensure that the drying agent does not chemically react with the substance being dried.

3. **Chemical Reaction Between Calcium Chloride and Ammonia**: When calcium chloride comes into contact with ammonia, a chemical reaction occurs. Calcium chloride can react with ammonia to form ammonium chloride (NH₄Cl). The reaction can be represented as:
