What is Cerium(III) bromide hydrate?
Description
Cerium(III) bromide hydrate is a compound with the molecular formula CeBr3 · H2O. It is composed of colorless needle-shaped crystals that are prone to deliquescence. Cerium(III) bromide is highly soluble in water and ethanol, and is also soluble in acetone. When exposed to heat, it decomposes. The solution of Cerium(III) bromide is neutral to Methyl orange solution, but acidic to litmus. It is recommended to store it in sealed containers.
Chemical properties
orange powder(s); hygroscopic [STR93]
