Hydrobromic Acid 48%

Hydrobromic acid, a potent acid, is produced by dissolving the diatomic molecule hydrogen bromide (HBr) in water. A variant known as "constant boiling" hydrobromic acid is an aqueous solution that distils at 124.3 °C, comprising 47.6% HBr by mass, equivalent to 8.77 mol/L. With a pKa of −9, hydrobromic acid exhibits more excellent acidity than hydrochloric acid but falls short of the strength observed in hydroiodic acid. Recognized as one of the most formidable mineral acids, hydrobromic acid holds a significant position in chemical reactivity.
