Sodium bromide

From Simple English Wikipedia, the free encyclopedia
Sodium bromide

Sodium bromide is a chemical compound. Its chemical formula is NaBr. It is made of sodium and bromide ions.

Properties[change | change source]

Sodium bromide is a white solid. It dissolves easily in water. When it is heated very strongly in air, it makes bromine gas. It also reacts with chlorine to make liquid bromine.

Preparation[change | change source]

It is made by reacting hydrogen bromide with sodium hydroxide. It can be made by mixing sodium and bromine, although this reaction is very violent.

Uses[change | change source]

It was used in medicine as a hypnotic and sedative.[1] Potassium bromide is also used for this purpose. It is used to make other bromine compounds that are organic.[2] It was used to make silver bromide. It can be used as a disinfectant with chlorine in pools. It can be used to make dense fluids for drilling oil wells.[3]

Safety[change | change source]

Sodium bromide is only toxic in large amounts, like sodium chloride.[4]
