…generic formula CaCl2·nH2O, where n = 0, 1, 2, 4, and 6. These compounds are mainly used for de-icing and dust control. Because the anhydrous salt is hygroscopic and deliquescent, it is used as a desiccant. Calcium chloride was apparently discovered in the 15th century but wasn't studied properly until the 18th century. It was…
