The hydrobromic acid formula, likewise recognized as the Hydrogen bromide formula is offered in this article. The is a diatomic molecule the subsists the a single covalent bond between the hydrogen and also bromine atoms. The is a very solid acid as the covalent bond can be conveniently ionized since of the high electronegativity of the Bromine atom. Therefore it is an ext capable 보다 hydrochloric acid. The chemical or molecular formula of Hydrobromic mountain is HBr.

You are watching: What is the formula for hydrobromic acid

In its anhydrous structure, it shows up as a colourless gas and its fumes have actually a pungent stroked nerves odour. It is colourless in that anhydrous form. In that is aqueous form, it arrives as a colourless to faint yellow liquid and also has one acrid odour. It is corrosive and a strong mineral acid. That is derived 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 the hydrogen. Hydrobromic acid is a diatomic molecule v the chemical formula because that hydrobromic mountain is HBr. Hydrogen bromide is a colourless, asphyxiating gas, an extremely soluble in water and also highly dissociated in one aqueous solution. That eagerly fumes in the presence of moist air. Hydrogen bromide gas is one eminently corrosive substance the can reason serious burns ~ above contact.

Hydrobromic acid Formula and Structure

When we describe the chemical formula that hydrobromic acid, which is aqueous hydrogen bromide, it is HBr. The molar fixed of hydrobromic acid is 80.9 g/mol.


Hydrobromic mountain Formula

This is one uncomplicated, diatomic molecule having actually a solitary covalent shortcut which is in between the bromine and hydrogen atoms. This bond can conveniently ionize (releasing H+) because of the high electronegativity of Br. Therefore, this reasons HBr come be rather a strong acid.


One can kind hydrobromic mountain on the laboratory scale after exhilaration bromine, sulfur dioxide through water. The will offer out sulphuric acid as a by-product.

Br2 + SO2 + 2 H2O → H2SO4 + 2 HBr

Looking in ~ the commercial extent, we watch that hydrobromic acid is likewise commonly occurred via the reaction that dilute sulphuric acid together with potassium bromide.

H2SO4 + KBr → KHSO4 + HBr

Therefore, in bespeak to do hydrobromic acid easily accessible in the commercial ar in different concentrations and also purities, we dilute the or command it.

Physical Properties

If you desire to learn about the actual physical properties the HBr favor the boil point, melting allude and density, it will certainly basically be dependent top top the concentration of that in the aqueous solution. Us detect that hydrobromic acid can typically be availed in a ‘constant boiling form’, which is an aqueous solution (around 48% w/w).

It is discovered to it is in colourless or in a an extremely pale yellow colour liquid. The thickness of hydrobromic acid is 1.49 g/mL. Likewise, once we look in ~ its cook point, the is 122-124 °C. Various other than that, that has gained quite a solid pungent odour.

Chemical Properties

Hydrobromic acid is claimed to be quite a solid mineral acid. Studies display that that is stronger than hydrochloric acid. It has actually a usual reaction through bases to create bromide salts. Further, HBr is also an extremely reactive and also corrosive to many of the metals.


Hydrobromic acid has numerous uses in many fields. In the industrial field, the is provided for creating multiple valuable inorganic bromides and also organobromine compounds. Because that example, zinc bromide, allyl bromide and also bromoacetic acid. Moreover, that is likewise a typical substance in necessary chemistry. The is therefore because, In organic chemistry, it has acquired uses in oxidation and also catalysis. Moreover, that is also a an extremely compelling chemical that we use to derive particular metal ores.

Health Hazards

Hydrobromic mountain is quite a corrosive acid that might induce major tissue damage. If you inhale the pungent fumes the Hydrobromic acid, you might suffer from irritation in the eyes and it have the right to contaminate her eyes and also mucous membranes, respiratory system. If girlfriend come in contact with this acid through the eyes or skin, friend may gain severe burns. Moreover, completely avoid swallowing together the acid will an outcome in bring about permanent organization damage.
