95%
- 100-325 mesh
232-164-6
Characteristic
Calcium bromide is the name for compounds with the chemical formula CaBr2(H2O)x. Individual compounds include the anhydrous material (x = 0), the hexahydrate (x = 6), and the rare dihydrate (x = 2). All are white powders that dissolve in water, and from these solutions crystallizes the hexahydrate.
Chemical formula: CaBr2•XH2O
Molar mass: 235.98 g/mol
Appearance: anhydrous is hygroscopic colorless crystals; sharp saline taste
Density: 3.353 g/cm3
Melting point: 730 °C (1,350 °F; 1,000 K)
Boiling point: 810 °C
Solubility in water: 125 g/100 mL (0 °C); 143 g/100 ml (20 °C); 312 g/100 mL (100 °C)
Solubility in alcohol, acetone: soluble
Acidity (pKa): 9
Magnetic susceptibility (χ): -73.8•10−6 cm3/mol
Application
Calcium bromide hydrate is used as freezing mixtures, food preservatives and photography. Its aqueous solution is used in drilling fluids and fire retardants.
