Calcium chloride - Simple English Wikipedia, the free …
Calcium chloride is a chemical compound made of calcium and chlorine atoms. It has the formula of CaCl 2.It absorbs water from the air and releases heat when it is dissolved in water. It is used as a de-icer on roads to melt the ice. It can be formed by mixture of calcium oxide with hydrochloric acid, but this produces a version that is hydrated (has water molecules attached to it).
