Hydrobromic Acid Formula, Structure & More

The hydrobromic Acid formula, additionally identified as the Hydrogen bromide formula, is given in this short article. It is a diatomic molecule that exists of a solitary covalent bond between the hydrogen and bromine atoms. It is a potent acid as the covalent bond can be quickly ionized because of the high electronegativity of the Bromine atom. As a result, it is more qualified than HCL. The molecular or chemical formula of Acid is HBr.

Its anhydrous framework looks like a colourless gas, and its fumes have a pungent irritating odour. It is colourless in its anhydrous type. Its liquid kind arrives as a colourless to pale yellow liquid and has an acrid smell. It is harsh and a solid mineral acid. It is achieved by softening the diatomic molecule, i.e., hydrogen bromide, in H2O.

What is Hydrobromic Acid?

Hydrobromic acid is a leading acid made up in the water by dissolving the bromide of hydrogen. It is a diatomic molecule with the formula for hydrobromic acid is HBr. Hydrogen bromide is a colourless, asphyxiating gas that is very soluble in water and very dissociated in an aqueous service. It excitedly fumes in the visibility of damp air. Hydrogen bromide gas is an incomparably corrosive material that can cause severe burns upon contact.

Hydrobromic Acid Formula and Structure

When we define the chemical formula of hydrobromic, liquid hydrogen bromide, it is HBr. The molar mass of hydrobromic acid is 80.9 g/mol.

This is an uncomplicated, diatomic molecule having a single covalent bond which is in between the bromine as well as hydrogen atoms. This bond can conveniently ionize (launching H+) due to the high electronegativity of Br. For that reason, this causes HBr to be rather a strong acid.


One can create hydrobromic acid on the laboratory scale after acting bromine, sulphur dioxide with water. It will break down sulphuric acid as a by product.

Br2 + SO2 + 2 H2O → H2SO4 + 2 HBr

Considering the commercial extent, we see that hydrobromic acid is likewise commonly developed via the reaction of weakening sulphuric acid along with potassium bromide.

H2SO4 + KBr → KHSO4 + HBr

For that reason, to make hydrobromic acid available in the industrial field in different focus and pureness, we weaken it or perform it.

Physical Properties

Suppose you intend to find out about the actual physical residential or commercial properties of HBr like the boiling point, melting point, and thickness. In that case, it will primarily be dependent on the focus of it in the liquid option. We identify that can commonly avail hydrobromic acid in a ‘constant boiling kind’, which is an aqueous option (around 48% w/w).

It is discovered to be colourless or in a highly light-yellow colour liquid. The thickness of hydrobromic acid is 1.49 g/mL. Furthermore, when we look at its boiling point, it is 122-124 ° C. Aside from that, it has a solid, poignant odour.

Chemical Structure

Hydrobromic acid is claim to be pretty a solid mineral acid. Research studies reveal that it is more potent than hydrochloric acid. It has a typical response with bases to generate bromide salts. Additionally, HBr is also responsive and destructive to a lot of the metals.


Hydrobromic acid has numerous usages in several fields. In the commercial area, it is use to create several beneficial inorganic bromides and organ bromine compounds. For example, zinc bromide, allyl bromide as well as bromoacetic acid. Moreover, it is additionally a usual material in natural chemistry. It is so, inorganic chemistry, it has usages in oxidation and catalysis. In addition, it is also a very compelling chemical that we utilize to obtain specific metal ores.

Wellness Hazards

Hydrobromic acid is instead a destructive acid that may induce significant tissue damage. Suppose you inhale the pungent fumes of Hydrobromic acid. In that case, you might experience inflammation in the eyes as well, as it can pollute your eyes and mucous membrane layers and the breathing system. If you contact this acid via the eyes or skin, you may obtain severe burns. Furthermore, entirely avoid ingesting as the acid will undoubtedly lead to causing long-term cells damages.
