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.

Obtained as a by-product in the manufacture of potassium chlorate. The white crystals, soluble in water and alcohol, are deliquescent and must be kept in a well-stoppered bottle. Calcium chloride was used in iodized collodion formulas and in collodion emulsions. It was also an important desiccating substance used in tin calcium tubes designed to store presensitized platinum papers.
