Sodium bromide

Properties change

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

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

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

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