More Scientific Information

Calcium Chloride is highly hydroscopic, which means that it readily takes up moisture from the air. In particular, Calcium Chloride is used to pack drying tubes to exclude atmospheric moisture from a reaction set-up while allowing gases to escape. It can also be added to liquids to remove suspended or dissolved water. In this capacity, it is known as a drying agent or desiccant.
