Physical properties
Caesium bromide is an ionic compound of caesium and bromine. It is a white or transparent solid with melting point at 636 °C that readily dissolves in water.
Uses
Cesium bromide is used as reagent, intermediate in pharmaceuticals.Cesium bromide crystals are used in scintillation counters to detect radiation. The compound is also used to coat the inside of fluorescent screens.
Safety
Moderately toxic by intraperitoneal route.When heated to decomposition it emits toxic fumes of Br-.
Synthesis
Caesium bromide can be prepared via following reactions:
Neutralization:
CsOH (aq) + HBr (aq) → CsBr (aq) + H2O (l)
Cs2(CO3) (aq) + 2 HBr (aq) → 2 CsBr (aq) + H2O (l) + CO2(g)
Metabolism
Bromide is mainly absorbed via inhalation, but may also enter the body through dermal contact. Bromine salts can be ingested. Due to its reactivity, bromine quickly forms bromide and may be deposited in the tissues, displacing other halogens.
