Description and Uses

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.

In the manufacture of other bromides; in the preparation of phosphors.
