Product Name:Potassium bromide
English Name:Potassium bromide
CAS No.:7758-02-3
Aliases:Standard solution
Molecular Formula:KBr
Physical Properties:Colorless crystalline or white powder with a strong salty taste, turning yellow upon exposure to light, slightly hygroscopic. Soluble in 1.5 ml water, 1 ml boiling water, 4.6 ml glycerol, 250 ml ethanol per gram; aqueous solution is neutral. Relative density 2.75, melting point 730°C, boiling point 1435°C, irritant.
