Hydrobromic acid is a strong acid formed by dissolving the diatomic
molecule hydrogen bromide (HBr) in
water. "Constant boiling" hydrobromic acid is an aqueous solution
that distills at 124.3 °C and contains 47.6% HBr by weight, which is
8.89 mol/L.
Detailed description
Hydrobromic acid has a pKa of
−9, making it a stronger acid than hydrochloric
acid, but not as strong as hydroiodic acid. Hydrobromic
acid is one of the strongest mineral
acids known.
Uses
Hydrobromic acid is mainly used for the production
of inorganic bromides, especially the bromides of zinc, calcium, and sodium. It
is a useful reagent for generating organobromine
compounds. Certain ethers are cleaved with HBr. It also catalyzes
alkylation reactions and the extraction of certain ores. Industrially significant
organic compounds prepared from hydrobromic acid include allyl bromide,
tetrabromobis(phenol), and bromoacetic acid.
