Title: Sodium Bromide
CAS Registry Number: 7647-15-6
Trademarks: Sedoneural
Molecular Formula: BrNa
Molecular Weight: 102.89
Percent Composition: Br 77.66%, Na 22.34%
Line Formula: NaBr
Literature References: Prepd commercially by adding some excess bromine to a sodium hydroxide soln forming a mixture of bromide and bromate. The reaction products are evaporated to dryness and treated with carbon to reduce the bromate to bromide. Prepn: J. H. van der Meulen,
