Sodium Bromide:

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. 

Sodium Bromide is used in photographic processing, as a chemical intermediate for the manufacture of various chemicals, and bromides. It is used for water clarification and oil well drilling muds & chemicals. Pharmaceutical grade is used in medicine as sedatives.

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

• Sodium Bromide is used as a hypnotic, anticonvulsant, and sedative in medicine.

• It is used as a source of the bromide ion, which is pharmacologically active.

• It is used in photography

• It is used to establish a bromide ion reserve in a bromine spa (hot tub) antimicrobial treatment regimen.

• It is used as pesticide

• It is used as destarching agent for cotton printing mill, also used for papermaking industry.

Safety

NaBr is harmful if swallowed or inhaled in large amounts, affecting the central nervous system, brain, and eyes. The chemical compound causes irritation to the skin, eyes and respiratory system.
