Calcium chloride (chemical blueprint CaCl2) is the ionic admixture of calcium and chlorine. It is a alkali that behaves as a archetypal ionic halide, getting solid at allowance temperature and awful acrid in water. Calcium chloride can serve as a antecedent of calcium ions in an aqueous solution, as calcium chloride is acrid in water. This acreage can be advantageous for displacing ions from solution. Common applications cover alkali for algidity plants, ice and dust ascendancy on roads, and desiccation. Because of its hygroscopic nature, alluring and captivation water, anhydrous calcium chloride have to be kept in closed containers.
