Because these salts can easily absorb water and become hydrates.

Anhydrous salts are hard to store because they readily absorb water from the atmosphere, forming hydrated salts. This can change their properties, such as solubility and reactivity, making them less predictable in reactions. Proper storage in airtight containers with desiccants is necessary to prevent moisture absorption.
Leaving a bottle of anhydrous sodium sulfate or calcium chloride open can lead to absorption of moisture from the air, causing them to become hydrated salts. This can compromise the purity and effectiveness of the reagents, affecting experimental results in chemistry.
Yes, an electrical spark can ignite an explosion with anhydrous ammonia as it is a flammable gas. This can occur if the concentration of ammonia in air is within the explosive range. It is important to handle and store anhydrous ammonia carefully to prevent such incidents.
Anhydrous crystals are likely to absorb moisture from the air, causing them to become hydrated. This can alter the crystalline structure and purity of the crystals. It is important to store anhydrous crystals in a dry environment to prevent moisture absorption.
The chemical symbol for Anhydrous Ammonia is NH3.
Theformula for anhydrous sodium carbonate is Na2CO3.
