Calcium bromide is a chemical compound with the formula CaBr₂. Here are some key details about it:
Properties:
- Appearance: White, crystalline solid (anhydrous) or colorless deliquescent crystals (dihydrate, CaBr₂·2H₂O).
- Molar Mass:
- Anhydrous: 199.89 g/mol
- Dihydrate: 235.98 g/mol
- Melting Point: ~730°C (anhydrous)
- Boiling Point: ~810°C (sublimes)
- Solubility: Highly soluble in water, alcohol, and acetone.
Preparation:
Calcium bromide can be synthesized by:
- Reaction of calcium carbonate (CaCO₃) with hydrobromic acid (HBr):CaCO3+2HBr→CaBr2+H2O+CO2↑CaCO3+2HBr→CaBr2+H2O+CO2↑
- Direct reaction of calcium metal with bromine:Ca+Br2→CaBr2Ca+Br2→CaBr2
Uses:
- Oil & Gas Industry: Used as a dense brine in drilling fluids.
- Photography: In some photographic compositions.
- Medicine: Occasionally used as a sedative (historically, now rare).
- Chemical Synthesis: As a source of bromide ions in reactions.
Safety:
- Irritant: Can cause skin and eye irritation.
- Hygroscopic: Absorbs moisture from the air (deliquescent).
- Toxicity: Moderately toxic if ingested in large amounts.
