General Description: Antimony tribromide (CAS NO.7789-61-9) is the yellow crystalline solid dissolved in hydrobromic acid. Antimony tribromide (CAS NO.7789-61-9) is decomposed by water giving an antimony oxide and hydrobromic acid. Antimony tribromide (CAS NO.7789-61-9) is corrosive to metals and tissue.
Air & Water Reactions: Water slowly hydrolyzes antimony tribromide to form antimony (III) oxide and hydrobromic acid. The dry powdered oxide ignites on heating in air.
Reactivity: Profile Acidic salts, such as Antimony tribromide (CAS NO.7789-61-9) , are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
Health Hazard: Antimony tribromide (CAS NO.7789-61-9) is toxic; If people inhalate, ingest or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.
