Calcium chloride hexahydrate Usage And Synthesis
  • Chemical PropertiesCalcium chloride is a colorless to off-white crystalline solid which is deliquescent (absorb water). When heated, crystals lose water @ 100C.
  • DefinitionChEBI: A hydrate that is the hexahydrate form of calcium chloride.
  • Potential ExposureCalcium chloride is used as road salt for melting snow, a drying agent in desiccators, for dehydrating organic liquids and gases, in refrigeration brines and antifreeze, as a dust-proofing agent, food additives, concrete hardening accelerator, and others. May react with strong oxidizers.
  • ShippingThere are no label or maximum shipping quantity requirements set by DOT.
  • IncompatibilitiesThe solution in water is a weak base. Reacts with zinc in presence of moisture, forming highlyflammable hydrogen gas. Dissolves violently in water with generation of much heat. Incompatible with water, bromine trifluoride; 2-furan, percarboxylic acid. May attack some building materials and metals in the presence of moisture.
