Properties

Hydrogen bromide is a colorless, heavier-than-air, toxic gas with an acrid odor. It is soluble in water, and its aqueous solution is a strong acid. Its chemical behavior is similar to hydrochloric acid: it reacts with metals, their oxides, hydroxides and carbonates. Its salts are called bromides.

Occurrence and production

Hydrogen bromide is produced in a reaction of hydrogen and bromine in the presence of a catalyst or in a reaction of hydrogen sulfide and bromine.

Uses

It is used in industrial quantities in the production of inorganic bromides and alkyl bromides.
