Description and Uses

Tumorigen,Mutagen, Human Data; Hormone. Calcium chloride is usedas road salt for melting snow, a drying agent in desiccators,for dehydrating organic liquids and gases, in refrigerationbrines and antifreeze, as a dust-proofing agent, food additive, concrete hardening accelerator, and others.Incompatibilities: The solution in water is a weak base.Reacts with zinc in presence of moisture, forming highly526 Calcium chlorideflammable hydrogen gas. Dissolves violently in waterwith generation of much heat. Incompatible with water,bromine trifluoride; 2-furan, percarboxylic acid. Mayattack some building materials and metals in the presenceof moisture.

Calcium chloride is highly hygroscopic and is often used as a desiccant.
