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.
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.
This forms hypobromous acid (HOBr), and hydrobromic acid (HBr in water). The solution is called "bromine water". The hydrolysis of bromine is more favorable in the presence of base, for example sodium hydroxide: Br 2 + NaOH → NaOBr + NaBr. This reaction is analogous to the production of bleach, where chlorine is dissolved in the presence of ...
Strong electrolytes conduct electricity only in aqueous solutions, or in molten salt, and ionic liquid. Strong electrolytes break apart into ions completely. The strength of an electrolyte does not affect the open circuit voltage produced by a galvanic cell. But when electric current flows, stronger electrolytes result in smaller voltage losses ...
The pure β form is obtained by heating the product to 470 °C and then rapidly cooling it in ice water. [2] ThO 2 + 2 C + 2 Br 2 ThBr 4 + 2 CO. Thorium(IV) bromide can also be produced by the reaction of thorium and bromine. Thorium hydroxide reacts with hydrobromic acid to crystallize hydrates from the solution. [3]
From numbers of equivalent portions of acid bromine formed from the previous reaction, the ratio between oxygen and bromine was calculated, with the exact value of O:Br (0.149975:0.3745), suggesting the acid compound contains two oxygen atom to one bromine atom. Thus, the chemical structure of the acid compound was deducted as HBrO 2. [2]
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 ...
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]
