CAS:10043-52-4
Molecular formula: CaCl2
Calcium chloride, consisting of chlorine and calcium, with the chemical formula of CaCl2. It is a typical ionic halide and a white solid at room temperature. It is applied to brine, road ice melting agent and desiccant used in refrigeration equipment. Because it is easy to absorb water and deliquesce in the air, anhydrous calcium chloride should be stored in sealed containers. Calcium chloride and its hydrates and solutions have important application values in food manufacturing, building materials, medicine and biology.
