CAS number : 10043-52-4
Molecular weight :110.98
Molecular formula/chemical symbol : CaCl2
Description :
Calcium chloride, CaCl2, is a salt of calcium and chloride. It behaves as a typical ionic halide, and is solid at room temperature. Common applications include brine for refrigeration plants, ice and dust control on roads, and desiccation. Because of its hygroscopic nature, anhydrous calcium chloride must be kept in tightly sealed, air-tight containers.
Keywords:Chloride
USES :
These hygroscopic properties are also applied to keep a liquid layer on the surface of the roadway, which holds dust down.
Aqueous calcium chloride is used in genetic transformation of cells by increasing the cell membrane permeability, inducing competence for DNA uptake (allowing DNA fragments to enter the cell more readily).
