74% Calcium Chloride White Powder Calcium Chloride Dihydrate Desiccant Refrigerant
Calcium chloride, whose chemical formula is CaCl2, is a chloride salt composed of chlorine and calcium. Odorless, slightly bitter taste, white solid at room temperature, a typical ionic halide. Calcium chloride generally exists in the form of white or off-white particles, spheres or powder. Easily soluble in water, its aqueous solution is slightly alkaline, and the household releases a lot of heat during the process of dissolving in water. In addition, calcium chloride is very hygroscopic, and it is easy to deliquesce when placed in the air, so the packaging must be tight.
