Potassium Bromide Chemical Formula: KBr Relative Molecular Mass: 119.00

It is a colorless crystal or white powder with a strong salty taste, and turns yellow when exposed to light. It is slightly hygroscopic. 1g dissolves in 1.5mL of water, and the aqueous solution is neutral. Its relative density (d254) is 2.75, melting point is 730℃, boiling point is 1435℃. It is irritating. It is mainly used in spectral analysis, spot analysis for copper and silver determination, polarographic analysis for indium, cadmium and arsenic, as a developer, and in pesticide analysis.

Properties Colorless crystal or white powder with a strong salty taste; turns yellow when exposed to light, slightly hygroscopic. 1g dissolves in 1.5mL of water, 1mL of boiling water, 4.6mL of glycerol, 250mL of ethanol; the aqueous solution is neutral. Its relative density (d254) is 2.75, melting point is 730℃, boiling point is 1435℃, and it is irritating.

Applications Used in spot analysis for copper and silver determination, polarographic analysis for indium, cadmium and arsenic, as a developer, and in pesticide analysis. In the photosensitive material industry, it is used to manufacture photographic films, developers, film intensifiers, toners and color photo bleaches; in medicine, it is used as a nerve sedative (tribromide tablets); it is also used as a chemical analysis reagent, for the transmission of spectroscopy and infrared rays, in the production of special soaps, as well as in engraving, lithography, etc.
