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.
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.
In chemistry, a hydrobromide is an acid salt resulting, or regarded as resulting, from the reaction of hydrobromic acid with an organic base (e.g. an amine). The compounds are similar to hydrochlorides. Some drugs are formulated as hydrobromides, e.g. eletriptan hydrobromide.
Silver bromide (AgBr). Nearly all elements in the periodic table form binary bromides. The exceptions are decidedly in the minority and stem in each case from one of three causes: extreme inertness and reluctance to participate in chemical reactions (the noble gases, with the exception of xenon in the very unstable XeBr 2; extreme nuclear instability hampering chemical investigation before ...

Another method is to neutralize rubidium carbonate with hydrobromic acid: Rb 2 CO 3 + 2 HBr → 2 RbBr + H 2 O + CO 2 Rubidium metal would react directly with bromine to form RbBr, but this is not a sensible production method, since rubidium metal is substantially more expensive than the carbonate or hydroxide; moreover, the reaction would be ...
Copper(II) bromide can be obtained by combining copper oxide and hydrobromic acid: [4] CuO + 2HBr → CuBr 2 + H 2 O. The tetrahydrate can be produced by recrystallization of solutions of copper(II) bromide at 0 °C. If heated above 18 °C, it releases water to produce the anhydrous form. [5]
As is expected, it may be prepared by reaction between phosphorus tribromide and acetic acid: [2] 3 CH 3 COOH + PBr 3 → 3 CH 3 COBr + H 3 PO 3. As usual for an acid halide, acetyl bromide hydrolyzes rapidly in water, forming acetic acid and hydrobromic acid. It also reacts with alcohols and amines to produce acetate esters and acetamides ...
