Hydrobromic Acid: Formula, Structure, Properties and Uses

This page contains the hydrobromic acid formula, also known as the hydrogen bromide formula. It’s a diatomic molecule with a single covalent link connecting the hydrogen and bromine atoms. Because of the high electro negativity of the Bromine atom, the covalent linkage can easily be ionised, making it an extremely strong acid. As a result, it outperforms hydrochloric acid. Hydrobromic acid has the chemical or molecular formula HBr.

It appears as a colourless gas in its anhydrous state, and its vapours have a harsh, irritating odour. In its anhydrous state, it is colourless. It comes in aqueous form as a colourless to pale yellow liquid with an unpleasant odour. It is a powerful mineral acid that is corrosive. We can make it by softening hydrogen bromide, a diatomic molecule, in water.

Hydrobromic Acid: What it is

HBr acid is a dominating acid made by dissolving hydrogen bromide in water. The chemical formula for hydrobromic acid is HBr. HBr acid is a diatomic molecule with the chemical formula HBr. Hydrogen bromide is a colourless, suffocating gas that is highly soluble in water and dissociated in an aqueous solution. In the presence of damp air, it eagerly fumes. Hydrogen bromide gas is a corrosive gas that can inflict severe burns if it comes into touch.

The diatomic molecule hydrogen bromide (HBr) is dissolved in water to produce hydrobromic acid, a powerful acid. The aqueous solution of “constant boiling” hydrobromic acid distils at 124.3 °C and contains 47.6% HBr by mass, or 8.77 mol/L. With a pKa of 9, hydrobromic acid is a more vital acid than hydrochloric acid but not as powerful as hydroiodic acid. One of the most potent mineral acids is HBr acid.

HBr Acid Uses

Hydrobromic acid is mainly used to make inorganic bromides, particularly zinc, calcium, and sodium bromides. It’s an excellent reagent for making organobromine compounds. With HBr, certain ethers can be cleaved. Alkylation processes and the extraction of some ores are also catalysed by it. Alkyl bromide, tetrabromobis(phenol), and bromoacetic acid are also industrially important organic chemicals made from hydrobromic acid. HBr nearly exclusively carries out Anti-Markovnikov hydrohalogenation of alkenes. The 1-Bromo alkanes that arise are versatile alkylating agents that produce fatty amines and quaternary ammonium salts.

HBr acid has a wide range of applications. In the industrial world, it’s utilised to make a variety of necessary inorganic and organobromine chemicals. Zinc bromide, allyl bromide, and bromoacetic acid, for example. It’s also a frequent chemical compound in organic chemistry. It’s because it’s common in organic chemistry for oxidation and catalysis. Furthermore, it is an enticing chemical that we use to extract specific metal ores.

HBr Acid Formula

The chemical formula for Hbr acid, often known as aqueous hydrogen bromide, is HBr. HBr acid also has a molar mass of 80.9 g/mol. This is a also a simple diatomic molecule with a single covalent link connecting the bromine and hydrogen atoms. Because of Br’s high electronegativity, this bond can efficiently ionise (releasing H+). As a result, HBr is a potent acid.

                                                          

                                                                      

HBr Acid Formation

We can also make HBr acid on a laboratory scale by reacting bromine, sulphur dioxide, and water. Though as a by-product, sulfuric acid will be there.

                                                 Br2 + SO2 + 2 H2O → H2SO4 + 2 HBr

When we look at the industrial scale, we can see that HBr acid is frequently made by reacting dilute sulphuric acid with potassium bromide.

                                                 H2SO4 + KBr → KHSO4 + HBr

As a result, we dilute or conduct HBr acid in order to make it commercially available in various concentrations and purities.

HBr Acid Physical Properties

If you want to understand the physical properties of HBr, such as its boiling point, melting temperature, and density, you’ll need to know how much of it is in an aqueous solution. Hbracid is typically available in a ‘constant boiling form,’ an aqueous solution (about 48 per cent w/w).

It usually appears to be either colourless or in a very pale yellow liquid. HBr acid has a density of 1.49 g/mL. Similarly, the boiling point of this substance is 122-124 °C. Aside from that, it has a powerful pungent odour.

Hbr Health Hazards

Hydrobromic acid is a highly corrosive acid that has the potential to cause significant tissue damage. If you inhale the harsh vapours of Hydrobromic acid, it can cause eye irritation and contamination of your eyes, mucous membranes, and respiratory system. You could get severe burns if you come into touch with this acid through your eyes or skin. Furthermore, avoid swallowing completely because the acid will cause irreversible tissue damage.

Most Commonly asked question on HBr

Therefore, we present the most asked question on hydrobromic acid.

Why HBr Is a Strong Acid

Weak acids only partially dissociate into their ions in water, whereas solid acids dissociate entirely. All of the other acids are ineffective. HCL acid, nitric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, perchloric acid, and chloric acid are examples of solid acids.
