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 ...
The effect of hydrobromic acid on a mixture of potassium bromide with rhenium(VI) oxide: [3] ReO 2 + 2KBr + 4HBr → K 2 ReBr 6 + 2H 2 O. Reduction of potassium perrenate by potassium iodide in concentrated hydrobromic acid: [3] 2KReO 4 + 6KI + 16HBr → 2K 2 ReBr 6 + 4KBr + 3I 2 + 8H 2 O
Thus, chemists distinguish hydrogen chloride from hydrochloric acid. The former is a gas at room temperature that reacts with water to give the acid. Once the acid has formed, the diatomic molecule can be regenerated only with difficulty, but not by normal distillation. Commonly the names of the acid and the molecules are not clearly ...
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]
Gadolinium(III) bromide can be obtained by the reaction between gadolinium and hydrobromic acid: [3] 2 Gd + 6 HBr → 2 GdBr 3 + 3 H 2 The anhydrous form can be obtained by heating the hydrate with ammonium bromide .
