hydrogen bromide
hydrogen \hy"dro*gen\ (?), n. [hydro-, 1 + -gen: cf. f. hydrogène. so called because water is generated by its combustion. see hydra.] (chem.) a gaseous element, colorless, tasteless, and odorless, the lightest known substance, being fourteen and a half times lighter than air (hence its use in filling balloons), and over eleven thousand times lighter than water. it is very abundant, being an ingredient of water and of many other substances, especially those of animal or vegetable origin. it may by produced in many ways, but is chiefly obtained by the action of acids (as sulphuric) on metals, as zinc, iron, etc. it is very inflammable, and is an ingredient of coal gas and water gas. it is standard of chemical equivalents or combining weights, and also of valence, being the typical monad. symbol h. atomic weight 1.
note: although a gas, hydrogen is chemically similar to the metals in its nature, having the properties of a weak base. it is, in all acids, the base which is replaced by metals and basic radicals to form salts. like all other gases, it is condensed by great cold and pressure to a liquid which freezes and solidifies by its own evaporation. it is absorbed in large quantities by certain metals (esp. palladium), forming alloy-like compounds; hence, in view of quasi-metallic nature, it is sometimes called hydrogenium. it is the typical reducing agent, as opposed to oxidizers, as oxygen, chlorine, etc.

Hydrogen bromide
Hydrogen bromide is the diatomic molecule HBr. Under standard conditions, HBr is a gas, but it can be liquified. The aqueous solution hydrobromic acid forms upon dissolving HBr in water. Conversely, HBr can be liberated from hydrobromic acid solutions upon the addition of a dehydration agents. Hydrogen bromide and hydrobromic acid are, therefore, not the same, but they are related. Commonly, chemists refer to hydrobromic acid as "HBr", and this usage, while understood by most chemists, is imprecise and can be confusing to the non-specialist.
