Tasteless odourless. There is a micro hygroscopicity in the air. Density 2.43 g/cm3. 452 °C sublimation. Soluble in water, alcohol, water solution is weak acid, slightly soluble in ether. Heating decomposition. Slight decomposition in the air, precipitation a small amount of bromine and make the color turn yellow. Ammonium bromide in bromide ion can be replaced by fluorine chlorine. Can be oxidated by strong oxidant such as chloric acid salt, potassium permanganate, concentrated nitric acid and concentrated sulfuric acid. an generate yellow silver bromide precipitation when react with silver bromide.   Ammonium Bromide Specification  Ammonium Bromide NH4Br molecular formulaNH4Br AAmmonium Bromide NH4Brmolecular formulaNH4Brmolecular weight97.94Cas No 12124-97-9 Ammonium Bromide Supplier Lubon Industry Co., Ltdmolecular formulaNH4Brmolecular weight97.94Cas No 12124-97-9H.S.
