Which type of salts are stored in air tight containers

Options

A. Anhydrous
B. Hydrated
C. Dehydrated
D. Deliquescence

Explanation

**Step-by-Step Solution:**

1. **Understanding the Types of Salts:**
- Salts can be classified into different categories based on their properties. The main types to consider are:
- Anhydrous salts
- Hydrated salts
- Deliquescent salts

2. **Definition of Deliquescent Salts:**
- Deliquescent salts are those that have the ability to absorb moisture from the air. This property makes them hygroscopic, meaning they can attract water vapor and dissolve in it.

3. **Reason for Storing in Airtight Containers:**
- Since deliquescent salts absorb moisture from the environment, if they are left exposed to air, they can dissolve and form a solution. To prevent this from happening, these salts are stored in airtight containers. This helps to keep them dry and prevents them from absorbing moisture.

4. **Examples of Deliquescent Salts:**
- Common examples of deliquescent salts include zinc chloride (ZnCl2) and calcium chloride (CaCl2). These salts are typically stored in airtight containers to maintain their solid form.

5. **Conclusion:**
- The type of salts that are stored in airtight containers are deliquescent salts due to their hygroscopic nature.

**Final Answer:**
Deliquescent salts are stored in airtight containers.
