Hydrogen Bromide Gas (HBr) Anhydrous What is hydrogen bromide? Anhydrous hydrogen bromide (HBr) is a corrosive, irritating, colorless, toxic gas that is delivered in liquid state under its own vapor pressure. Hydrogen bromide is created as a result of the reaction between highly pure hydrogen and elemental bromine, along with the reaction between sulfuric acid and specific brominated metals.
