Product Description

Calcium chloride, a salt composed of chlorine and calcium, has a chemical formula of CaCl2. Bitter and tasteless. It is a typical ionic halide and is white, hard fragments or granules at room temperature. Its common applications include brine, road ice melting agent and desiccant for refrigeration equipment. It is anhydrous or contains two molecules of water of hydration. It is deliquescent. It is soluble in water and slightly soluble in alcohol. Anhydrous calcium chloride must be stored in a sealed container because it is easy to absorb moisture in the air for hygrolysis. Calcium chloride and its hydrates and solutions have important application value in food manufacturing, building materials, medicine and biology. Calcium chloride has outstanding adsorption capacity for ammonia and low desorption temperature, so it has a great application prospect in the adsorption and separation of synthetic ammonia. It is anhydrous or contains two molecules of water of hydration. It is deliquescent. It is soluble in water and slightly soluble in alcohol. The Calcium Chloride pH of a 1:20 aqueous solution is between 4.5 and 11.0.
