| Hazard Information | Back Directory | [Description]
Barium 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 Properties]
White Crysatalline Powder | [Physical properties]
White 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). | [Uses]
Barium 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. | [Uses]
Barium bromide, anhydrous is used as the chemical intermediate, and the spice cosmetics chemical additive. It is also used as pharmaceutical intermediate. | [Uses]
In the manufacture of other bromides; in the preparation of phosphors. | [Preparation]
Barium 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 | [Hazard]
Ingestion of the salt or its aqueous solution can produce severe poisoning. |
