What is "hydrobromic acid"

Hydrobromic \Hy`dro*bro"mic\, a. [Hydro-, 2 + bromic.] (Chem.) Composed of hydrogen and bromine; as, hydrobromic acid.

Hydrobromic acid (Chem.), a colorless, pungent, corrosive gas, HBr, usually collected as a solution in water. It resembles hydrochloric acid, but is weaker and less stable. Called also hydrogen bromide.

n. (context inorganic compound English) A solution of hydrogen bromide, HBr, in water; it is a strong acid, used in the production of bromine compounds.

n. an aqueous solution of hydrogen bromide that is a strong liquid acid

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. Hydrobromic acid has a pK 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.
