What is Strontium bromide?
Description
Strontium bromide has the formula SrBr2. At room
temperature, it is a white, odorless, crystalline powder
with the molecular weight of 247.43 g/mol. Strontium
bromide burns bright red in a flame test. It is used in
flares and also has some pharmaceutical uses. Several
hydrates have been characterized including the monohydrate
and the hexahydrate, SrBr2·6H2O. This salt is
a white, hygroscopic powder soluble in water and
alcohol. It loses water at 180°C, melts at 643°C and is
used in medicine and as an analytical reagent.
The anhydrate, SrBr2, is a colorless, transparent,
crystal, odorless, having a bitter, saline taste. It is very
deliquescent and soluble in water and is readily soluble
in alcohol and amyl alcohol. The specific gravity of SrBr2
is 4.210 g/cm3. It can be prepared by treating SrCO3 with
a hydrogen bromide solution. Alternatively, a strontium salt (carbonate, sulfate, chloride, etc.) is treated with bromine or hydrobromic acid in presence of a reducing agent.
Chemical properties
White crystalline powder
The Uses of Strontium bromide
Strontium bromide are colorless crystals made by neutralizing hydrobromic acid with strontium hydrate. The crystals are soluble in water but less so in alcohol. Strontium bromide was occasionally used to increase contrast in collodion emulsions.
The Uses of Strontium bromide
Reagent for facile synthesis of poly(phenylcarbyne), a precursor to diamond-like carbon.1
The Uses of Strontium bromide
Also has some pharmaceutical uses
Hazard
Toxic by ingestion and inhalation.
Purification Methods
Crystallise the bromide from water (0.5mL/g). It is deliquescent. [Ehrlich in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 930 1963.]
