Hydrobromic acid molar mass, uses, and other properties

What is Hydrobromic acid?

Hydrobromic acid is a colorless liquid formed by dissolving HBr in water. It is easily soluble in water and is one of the strong acids that we know. Hydrobromic acid is stronger than Hydrochloric acid and is among the strongest mineral acids. It is also highly corrosive and also fumes when it comes in contact with moist air. Hydrobromic acid is synthesized in the laboratory using Bromine, Sulphur Dioxide, and water.

Uses of the Hydrobromic acid

  • Hydrobromic acid is used as a reagent used in the production of organobromine compounds. 
  • It is also used in producing inorganic bromides such as the bromides of zinc, sodium, and calcium.
  • The acid is also used as a catalyst in the extraction of the ores and also for alkylation reactions.


To read, write and know something new every day is the only way I see my day! Well, that rhymed. Hey folks, this is me, Priyanka, writer at Geometry of Molecules where I want to make Chemistry easy to learn and quick to understand. Having an MSc degree helps me explain these concepts better. I write all the blogs after thorough research, analysis and review of the topics. And if not writing you will find me reading a book in some cosy cafe!
