A chemical compound having the formula HBr which appears under the form of a colorless, nonflammable gas, is soluble in water and alcohol, is derived by passing hydrogen with bromine vapor over warm platinum sponge that acts as a catalyst or as a by-product in the bromination of organic compounds, and is used in organic synthesis, to make bromides by direct reaction with alcohols, as a pharmaceutical intermediate, an alkylation and oxidation catalyst, and a reducing agent.  2, fiche 2, Anglais, - hydrogen%20bromide

Hydrobromic acid is prepared by dissolving gaseous hydrogen bromide... with sulfuric acid.... Hydrobromic acid is a strong acid, i. e., in water the compound is highly dissociated to hydronium and bromide ions. It resembles hydrochloric acid in its activity toward metals or their oxides and hydroxides, forming bromine salts(bromides) and, with certain metals, complex bromine-containing ions.  2, fiche 3, Anglais, - hydrobromic%20acid
