What is Calcium chloride hexahydrate?

Chemical properties

Calcium chloride is a colorless to off-white crystalline solid which is deliquescent (absorb water). When heated, crystals lose water @ 100C.

The Uses of Calcium chloride hexahydrate

Calcium chloride hexahydrate has been used as a test compound for measuring the overall activity of low-molecular-weight antioxidants in biological samples by using ′total antioxidative capacity′ inhibition assay.

The Uses of Calcium chloride hexahydrate

Calcium chloride hexahydrate is a phase changing material (PCM) that is widely used in solar energy storage and building applications.

What are the applications of Application

Calcium chloride hexahydrate is used as a source of calcium ions in a solution

Definition

ChEBI: A hydrate that is the hexahydrate form of calcium chloride.

General Description

Calcium chloride hexahydrate is a non-toxic salt hydrate that can be used in phase change heat storage of low temperature heat. It has a latent heat of fusion as high as 170-190 kJ/Kg and a melting temperature of 29-30°C.

Biochem/physiol Actions

Calcium chloride act as precipitants during protein crystallization process. It also enhances the competence of Escherichia coli cells in transformation experiments. It strengthen β-lactoglobulin gels by forming crossbridges.

Potential Exposure

Calcium 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.

Shipping

There are no label or maximum shipping quantity requirements set by DOT.

Incompatibilities

The 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.
