Bromic acid is the product of a reaction of barium bromate and sulfuric acid. [1] Ba(BrO 3) 2 + H 2 SO 4 → 2 HBrO 3 + BaSO 4. Barium sulfate is insoluble in water and forms a precipitate. The aqueous bromic acid can be decanted removing the barium sulfate.
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.
Hypobromous acid has a pK a of 8.65 and is therefore only partially dissociated in water at pH 7. Like the acid, hypobromite salts are unstable and undergo a slow disproportionation reaction to yield the respective bromate and bromide salts. 3 BrO − (aq) → 2 Br − (aq) + BrO − 3 (aq)
The classic case is sodium bromide, which fully dissociates in water: NaBr → Na + + Br −. Hydrogen bromide, which is a diatomic molecule, takes on salt-like properties upon contact with water to give an ionic solution called hydrobromic acid. The process is often described simplistically as involving formation of the hydronium salt of bromide:
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]
Bromous acid is a product of the Belousov–Zhabotinsky reaction resulting from the combination of potassium bromate, cerium(IV) sulfate, propanedioic acid and citric acid in dilute sulfuric acid. Bromous acid is an intermediate stage of the reaction between bromate ion (BrO − 3) and bromine (Br −): [5] [6] BrO − 3 + 2 Br − → HBrO 2 ...
The four oxoacids, hypobromous acid (HOBr), bromous acid (HOBrO), bromic acid (HOBrO 2), and perbromic acid (HOBrO 3), are better studied due to their greater stability, though they are only so in aqueous solution. When bromine dissolves in aqueous solution, the following reactions occur: [10]
