sodium bromide

[′sōd·ē·əm ′brō‚mīd]
(inorganic chemistry)
NaBr White, water-soluble, crystals with a bitter, saline taste; absorbs moisture from air; melts at 758°C; used in photography and medicine, as a chemical intermediate, and to make bromides.

Sodium Bromide


NaBr, a salt; colorless crystals. Density, 3.20 g/cm3; melting point, 760°C. Solubility in water, 48.6 percent at 25°C and 54.8 percent at 100°C; NaBr-2H20 crystallizes from aqueous solutions at ordinary temperatures. Sodium bromide is prepared upon interaction of bromide with NaOH solutions in the presence of reducing agents or by an exchange reaction between Fe3Brs and Na2C03. It is used in the manufacture of photosensitive materials (silver bromide films and paper), and also in medicine (as a sedative and soporific).
