Facts About Calcium Chloride | Sciencing

Calcium chloride (CaCl2) is a calcium salt of hydrochloric acid. It is a deliquescent salt, meaning it can liquefy by absorbing moisture in the air. It is used to maintain calcium levels in water, as a drying agent to melt ice, can be used to strengthen concrete and is used in fire extinguishers.
