BARIUM BROMIDE Usage And Synthesis
DescriptionBarium bromide has the molecular formula of BaBr2. Like barium chloride, it is soluble in water but is toxic if ingested. BaBr2 crystallizes in a PbCl2 motif, as white orthorhombic crystals that are deliquescent. In aqueous solution, BaBr2 behaves as a simple salt.
Barium bromide can be crystallized from its solution as a dihydrate, BaBr2·2H2O (molecular weight: 333.19), which forms the anhydrate by heating to 120°C. It dissolves in its own water-of-hydration at 75°C before decomposing to the anhydrate.
Chemical PropertiesWhite Crysatalline Powder
Physical propertiesWhite orthorhombic crystal; density of anhydrous BaCl2 4.78 g/cm3, and dihydrate BaCl2 ? 2H2O 3.58 g/cm3; melts at 857°C; vaporizes at 1,835°C; readily dissolves in water (92.2 g/100 g water at 0°C).
UsesBarium bromide, anhydrous is used as the chemical intermediate, and the spice cosmetics chemical additive. It is also used as pharmaceutical intermediate.
UsesIn the manufacture of other bromides; in the preparation of phosphors.
UsesBarium bromide is a precursor to chemicals used in photography as well as to form other bromides.Historically, barium bromide was used to purify radium in a process of fractional crystallization devised by Marie Curie. Since radium precipitates preferentially in a solution of barium bromide, the ratio of radium to barium in the precipitate was found to be higher than the ratio in the solution.
PreparationBarium bromide can be prepared from barium sulfide or barium carbonate by reaction with hydrobromic acid to give hydrated barium bromide:
BaS+HBr→BaBr2+H2S
BaCO3+HBr→BaBr2+CO2+H2O

HazardIngestion of the salt or its aqueous solution can produce severe poisoning.
