Sodium bromite is an inorganic chemical compound of sodium from the bromite group .

Extraction and presentation

Sodium bromite can be obtained by reacting strontium bromite with sodium carbonate .

Sodium bromite can also be made by a relatively complex method in which the compound is made from sodium hydroxide , bromine and chlorine .

properties

Sodium bromite is a pale yellowish solid that is soluble in water. The compound and its trihydrate are not stable in air. They attract moisture and thereby decompose. Their aqueous solutions have an alkaline reaction and are also unstable, with the addition of alkali causing stabilization. Sodium bromite is a powerful oxidizer. The trihydrate has a triclinic crystal structure with the space group P 1 (space group no. 2) . Template: room group / 2

The compound decomposes at temperatures above 100 ° C.
