Calcium chloride is a salt with the chemical formula CaCl2. At room temperature, it is a white colored crystalline solid, and is extremely water soluble. It can be formed by neutralizing the calcium hydroxide hydrochloric acid. Calcium chloride is commonly used as an additive for enhancing  processes and features in plastics, wastewater treatment plants, and blast furnaces.  Calcium chloride, used as an agent to lower the freezing point of water, is very effective in preventing ice forming on road surfaces and to use as a deicer. Cacl2 is used a food additive and in the manufacturing of foods. It is used in salt production without increasing the sodium content to give a salty flavor to pickles and other foods. Spraying calcium chloride on fruit and vegetables increases longevity and shelf life.
