Hydrobromic acid (HBr) is a strong, corrosive acid formed by dissolving hydrogen bromide gas in water. It is a clear or slightly yellow liquid with a pungent odor and is highly soluble in water.
Key Properties:
- Chemical Formula: HBr (aqueous)
- Molar Mass: 80.91 g/mol (HBr gas)
- Appearance: Colorless to pale yellow liquid
- Odor: Pungent, irritating
- Acidity: Strong acid (completely dissociates in water: HBr→H++Br−HBr→H++Br−)
- pKa: ≈ −9 (extremely acidic)
- Boiling Point: ~126 °C (azeotrope with water at 47.6% HBr)
Uses of Hydrobromic Acid:
- Chemical Synthesis:
- Production of bromides (e.g., sodium bromide, potassium bromide).
- Catalyst in organic reactions (e.g., alkylation, oxidation).
- Used in the synthesis of pharmaceuticals and dyes.
- Industrial Applications:
- Etching agent in semiconductor manufacturing.
- Electrolyte in some batteries.
- Laboratory Use:
- Source of bromide ions in chemical reactions.
- Used in the preparation of bromine compounds.
Safety & Handling:
- Corrosive: Causes severe burns to skin and eyes.
- Toxic Fumes: Releases irritating and harmful vapors.
- Storage: Keep in tightly sealed containers, away from bases and metals.
- PPE Required: Gloves, goggles, and acid-resistant clothing.
Comparison with Hydrochloric Acid (HCl):
- HBr is stronger (lower pKa) than HCl.
- Bromide ion (Br−Br−) is a better nucleophile & leaving group than chloride (Cl−Cl−).
