Hydrogen bromide is the inorganic compound with the formula HBr. It is a hydrogen halide consisting of hydrogen and bromine. A colorless gas, it dissolves in water, forming hydrobromic acid , which is saturated at 68.85% HBr by weight at room temperature.
Bromide is present in typical seawater (35 PSU) with a concentration of around 65 mg/L, which is about 0.2% of all dissolved salts. Seafood and deep sea plants generally have higher levels than land-derived foods. Bromargyrite—natural, crystalline silver bromide—is the most common bromide mineral known but is still very rare. In addition to ...
Unlike hydrogen fluoride, anhydrous liquid hydrogen bromide is difficult to work with as a solvent, because its boiling point is low, it has a small liquid range, its dielectric constant is low and it does not dissociate appreciably into H 2 Br + and HBr − 2 ions – the latter, in any case, are much less stable than the bifluoride ions (HF −

A hydrogen–bromine battery is a rechargeable flow battery in which hydrogen bromide (HBr) serves as the system’s electrolyte.During the charge cycle, as power flows into the stack, H 2 is generated and stored in a separate tank, the other product of the chemical reaction is HBr 3 which accumulates in the electrolyte.
Breathing in gas with more than fifty parts per million of hydrogen chloride can cause death in humans. [18] Hydrogen bromide is even more toxic and irritating than hydrogen chloride. Breathing in gas with more than thirty parts per million of hydrogen bromide can be lethal to humans. [19] Hydrogen iodide, like other hydrogen halides, is toxic ...
Hydrobromic acid is an aqueous solution of hydrogen bromide.It 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 (255.7 °F) and contains 47.6% HBr by mass, which is 8.77 mol/L. Hydrobromic acid is one of the strongest mineral acids known.
