Calcium Chloride is a highly soluble, colorless salt that absorbs moisture from the environment. Here are some key details:

Chemical Formula: CaCl₂

Physical Form: Typically found as a white crystalline solid, flakes, granules, or pellets.

Solubility: Highly soluble in water and releases heat when dissolved (exothermic reaction).

Uses:

1. De-icing roads and sidewalks due to its ability to lower the freezing point of water.
2. Desiccant for moisture control (in packaging, storage, etc.).
3. Food Additive (E509) used in food processing for firming, preservation, and flavor.
4. Concrete Additive: Accelerates the setting time.

Health and Safety: Can be an irritant to the skin and eyes. Ingestion or large exposure can be harmful.

Natural Occurrence: Found in sea water and some mineral deposits (such as limestone).
Its hygroscopic nature makes it useful in applications that require moisture control.
