The hydrobromic acid formula, additionally recognized together the Hydrogen bromide formula is provided in this article. It is a diatomic molecule the subsists the a solitary covalent bond in between the hydrogen and also bromine atoms. That is a very strong acid as the covalent bond can be conveniently ionized since of the high electronegativity of the Bromine atom. As such it is an ext capable than hydrochloric acid. The chemistry or molecule formula the Hydrobromic mountain is HBr.

In its anhydrous structure, it shows up as a colourless gas and its fumes have a pungent stroked nerves odour. The is colourless in its anhydrous form. In that is aqueous form, it arrives together a colourless to faint yellow liquid and has an acrid odour. It is corrosive and a strong mineral acid. It is obtained by softening the diatomic molecule i.e hydrogen bromide in water.

What is Hydrobromic Acid?

Hydrobromic acid is a dominant acid composed in water by dissolve the bromide of hydrogen. Hydrobromic acid is a diatomic molecule through the chemical formula because that hydrobromic acid is HBr. Hydrogen bromide is a colourless, asphyxiating gas, really soluble in water and highly dissociated in an aqueous solution. The eagerly fumes in the visibility of moist air. Hydrogen bromide gas is one eminently corrosive substance that can reason serious burns ~ above contact.

Other names: Hydrogen bromide, bromane, HBr, Hydrobromic AcidDensity: 1.49 g/cm³Molecular Weight/ Molar Mass: 80.9119 g/molBoiling Point: 122 °CMelting Point: -11 °CChemical Formula: HBr

Hydrobromic mountain Formula and Structure

When we explain the chemistry formula of hydrobromic acid, i m sorry is aqueous hydrogen bromide, the is HBr. The molar massive of hydrobromic mountain is 80.9 g/mol.


Hydrobromic acid Formula

This is an uncomplicated, diatomic molecule having actually a single covalent bond which is in between the bromine and hydrogen atoms. This link can easily ionize (releasing H+) because of the high electronegativity that Br. Therefore, this causes HBr to be rather a strong acid.


One can kind hydrobromic acid on the laboratory range after exhilaration bromine, sulfur dioxide v water. It will give out sulphuric mountain as a by-product.

Br2 + SO2 + 2 H2O → H2SO4 + 2 HBr

Looking in ~ the commercial extent, we check out that hydrobromic mountain is likewise commonly emerged via the reaction of dilute sulphuric acid together with potassium bromide.

H2SO4 + KBr → KHSO4 + HBr

Therefore, in order to make hydrobromic acid accessible in the commercial ar in different concentrations and also purities, us dilute the or command it.

Physical Properties

If you want to learn about the actual physics properties that HBr like the boil point, melting allude and density, it will basically it is in dependent ~ above the concentration of the in the aqueous solution. Us detect the hydrobromic acid can frequently be availed in a ‘constant cook form’, i beg your pardon is an aqueous equipment (around 48% w/w).

It is discovered to it is in colourless or in a very pale yellow color liquid. The density of hydrobromic mountain is 1.49 g/mL. Likewise, as soon as we look in ~ its cook point, the is 122-124 °C. Various other than that, that has acquired quite a strong pungent odour.

Chemical Properties

Hydrobromic mountain is claimed to be fairly a strong mineral acid. Studies present that it is stronger than hydrochloric acid. It has actually a usual reaction through bases to develop bromide salts. Further, HBr is also very reactive and corrosive to many of the metals.


Hydrobromic acid has countless uses in plenty of fields. In the commercial field, the is provided for building multiple helpful inorganic bromides and also organobromine compounds. Because that example, zinc bromide, allyl bromide and bromoacetic acid. Moreover, it is additionally a usual substance in necessary chemistry. The is so because, In organic chemistry, that has gained uses in oxidation and catalysis. Moreover, that is likewise a really compelling chemical the we use to derive details metal ores.

Health Hazards

Hydrobromic acid is fairly a corrosive mountain that may induce major tissue damage. If girlfriend inhale the pungent fumes that Hydrobromic acid, you might suffer from wake up in the eyes and it have the right to contaminate your eyes and mucous membranes, respiratory system. If you come in contact with this acid v the eye or skin, friend may acquire severe burns. Moreover, fully avoid swallowing together the mountain will result in causing permanent tissue damage.
