The Industrial Appliions of Calcium Chloride
As Calcium Chloride absorbs water, it forms hydrated forms of Calcium Chloride. There are at least 4 levels of hydration of Calcium Chloride - 1, 2, 4 and 6-Hydrate. As water is absorbed, the hydration level increases until, depending on temperature, the Calcium Chloride will dissolve and become a highly concentrated liquid.
