Calcium chloride hexahydrate

Description:
Calcium chloride hexahydrate, with the chemical formula CaCl₂·6H₂O and CAS number 7774-34-7, is an inorganic compound that appears as a white crystalline solid. It is highly soluble in water, and its dissolution is accompanied by an exothermic reaction, making it useful as a de-icing agent and in various industrial applications. The hexahydrate form contains six water molecules per formula unit, contributing to its hygroscopic nature, which allows it to absorb moisture from the environment. This property makes it effective as a drying agent in various chemical processes. Calcium chloride hexahydrate is also used in food preservation, as a firming agent in canned vegetables, and in the production of calcium-based compounds. It is generally considered safe for use in food applications, although care should be taken to avoid excessive consumption. In terms of safety, it can cause irritation to the skin and eyes upon contact, and inhalation of dust may lead to respiratory discomfort. Proper handling and storage are essential to mitigate these risks.
