Calcium chloride (CaClâ‚‚) is an inorganic salt composed of calcium and chlorine. It is commonly used for various applications, including:
-
Deicing and Dust Control: CaClâ‚‚ is frequently used to deice roads and highways in winter, as it lowers the freezing point of water. It can also be used for dust control on unpaved roads.
-
Food Industry: It is used as a food preservative, as a firming agent in canned vegetables, and in the production of cheese.
-
Desiccant: Calcium chloride is hygroscopic, meaning it can absorb moisture from the air, making it useful as a desiccant for keeping environments dry.
-
Chemical Reagent: It is used in various chemical reactions and processes, including the preparation of other calcium compounds.
-
Construction: It can accelerate the setting time of concrete and is used in some formulations for grout and other construction materials.
Calcium chloride is typically available in anhydrous form or as a dihydrate. It is important to handle it with care, as it can be irritating to the skin and eyes and should be used with proper safety precautions.
