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.

ZnBr 2 · 2H 2 O is prepared by treating zinc oxide or zinc metal with hydrobromic acid. [1]ZnO + 2 HBr + H 2 O → ZnBr 2 ·2H 2 O Zn + 2 HBr → ZnBr 2 + H 2. The anhydrous material can be produced by dehydration of the dihydrate with hot CO 2 or by reaction of zinc metal and bromine. [2]
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 ...
TEAB catalyzes the high-yield oxidation of organic sulfides to sulfoxides by o-iodoxybenzoic acid (IBX) in chloroform/water at room temperature, [4] e.g. (C 2 H 5) 2 S → (C 2 H 5) 2 S=O. TEAB has been used for the in situ preparation of tetraethylammonium superoxide from potassium superoxide for the conversion of primary alkyl halides to ...
Ammonium bromide, NH 4 Br, is the ammonium salt of hydrobromic acid. The chemical crystallizes in colorless prisms, possessing a saline taste; it sublimes on heating and is easily soluble in water. On exposure to air it gradually assumes a yellow color because of the oxidation of bromide (Br −) to bromine (Br 2).
