Sodium Bromide General & Uses
Sodium bromide is a salt with the formula NaBr, widely used as an anticonvulsant and a sedative in the late 19th and early 20th centuries. Its action is due to the bromide ion (potassium bromide is equally effective). It is a high-melting white, crystalline solid that resembles sodium chloride. It is a widely used source of the bromide ion.
Principal chemical reactions
NaBr is widely used in organic synthesis as a nucleophile to convert organochlorine compounds to organobromine derivatives, which are more usefully (selectively) reactive.
NaBr + RCl → RBr + NaCl
Sodium bromide can be used as a source of the chemical element bromine. This can be accomplished by bubbling chlorine gas through an aqueous solution of NaBr.
As a source of HBr, NaBr is treated with a strong, non-volatile acid:
NaBr + H3PO4 → HBr + NaH2PO4
HBr can also be oxidized to Br2 using MnO2 or concentrated H2SO4.
Other Applications
Used as a hypnotic, anticonvulsant, and sedative in medicine. As a source of the bromide ion, which is pharmacologically active, it is equivalent to potassium bromide (see this article for more complete discussion of this topic).
In photography
Used to establish a bromide ion reserve in a bromine spa (hot tub) antimicrobial treatment regimen.
