What is a Calcium chloride (CaCl₂) ?

Calcium chloride (CaCl₂) is an inorganic compound composed of calcium and chlorine. It appears as a colorless or white crystalline solid and is highly soluble in water, releasing significant heat upon dissolution. This characteristic makes calcium chloride widely used as a deicer and desiccant. Calcium chloride is commonly used to prevent road icing and as a snow-melting agent, especially in winter. It plays a vital role in melting ice and snow in cold weather conditions. In the chemical industry, it is used as a desiccant to absorb moisture, making it helpful for storing materials in humid environments.

Additionally, calcium chloride is used in water treatment as a softening agent to reduce water hardness. It is also utilized as a food additive to maintain firmness, particularly in canned vegetables and juices.

When handling calcium chloride, care must be taken due to its strong hygroscopic nature, and it should not come into direct contact with the skin.
