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.
The disproportionation reaction of two equivalents hypobromous acid (HBrO) results in the formation of both bromous acid (HBrO 2) and hydrobromic acid (HBr): [citation needed] 2 HBrO → HBrO 2 + HBr. A rearrangement reaction, which results from the syn-proportion of bromic acid (HBrO 3) and hydrobromic acid (HBr) gives bromous acid (HBrO 2 ...
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:
Bromic acid, also known as hydrogen bromate, is an oxoacid with the molecular formula HBrO 3. It only exists in aqueous solution. [1] [2] It is a colorless solution that turns yellow at room temperature as it decomposes to bromine. [1] [3] Bromic acid and bromates are powerful oxidizing agents and are common ingredients in Belousov ...
So-called "bromine dioxide", a pale yellow crystalline solid, may be better formulated as bromine perbromate, BrOBrO 3. It is thermally unstable above −40 °C, violently decomposing to its elements at 0 °C. Dibromine trioxide, syn-BrOBrO 2, is also known; it is the anhydride of hypobromous acid and bromic acid. It is an orange crystalline ...
SrBr 2 can be prepared from strontium hydroxide and hydrobromic acid. Sr(OH) 2 + 2 HBr → SrBr 2 + 2 H 2 O. Alternatively strontium carbonate can also be used as strontium source. SrCO 3 + 2 HBr → SrBr 2 + H 2 O + CO 2 . These reactions give hexahydrate of strontium bromide (SrBr 2 ·6H 2 O), which decomposes to dihydrate (SrBr 2 ·2H 2 O ...
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]
