The … Hydrogen bromide is the inorganic compound with the formula HBr. It is a hydrogen halide consisting of hydrogen and bromine. A colorless gas, it dissolves in water, forming hydrobromic acid, which is saturated at 68.85% HBr by weight at room temperature. Aqueous solutions that are 47.6% HBr by mass form … See more Organic chemistry Hydrogen bromide and hydrobromic acid are important reagents in the production of organobromine compounds. In a free-radical reaction, HBr adds to alkenes: RCH=CH2 + HBr … See more Hydrogen bromide (along with hydrobromic acid) is produced by combining hydrogen and bromine at temperatures between 200 and 400 °C. The reaction is typically catalyzed by platinum or asbestos. See more HBr is highly corrosive and, if inhaled, can cause lung damage. See more HBr can be prepared by distillation of a solution of sodium bromide or potassium bromide with phosphoric acid or sulfuric acid: KBr + H2SO4 → KHSO4 + HBr Concentrated sulfuric acid is less effective because it oxidizes HBr to bromine: 2 HBr + H2SO4 → … See more
