As in the case of chlorine, bromine can be prepared by the action of hydrobromic acid (HBr) on manganese dioxide.
Hydrobromic acid in ethereal solution gives furfurane derivatives.
The hydrobromic acid is collected in the same way as hydrochloric acid.
Hydrobromic acid gas is colourless and non-inflammable; it extinguishes flame.
Hydrobromic acid very strikingly resembles hydrochloric acid in physical and chemical properties.
