Sodium bromite is a sodium salt of bromous acid. Its trihydrate , NaBrO 2 ·3H 2 O, has been isolated in crystal form. It is used by the textile refining industry as a desizing agent for oxidative starch removal.
Sodium bromide is an inorganic compound with the formula Na Br. It is a high-melting white, crystalline solid that resembles sodium chloride . It is a widely used source of the bromide ion and has many applications.
Sodium bromate can be produced from a solution of sodium carbonate and bromine using chlorine gas as the oxidising agent. [1] 6 Na 2 CO 3 + Br 2 + 5 Cl 2 → 2 NaBrO 3 + 10 NaCl + 6 CO 2. It may also be produced by the electrolytic oxidation of aqueous sodium bromide. [2]
The bromite ion in sodium bromite. The salts NaBrO 2 ·3H 2 O and Ba(BrO 2) 2 ·H 2 O have been crystallized. Upon treatment of these aqueous solutions with salts of Pb 2+, Hg 2+, and Ag +, the corresponding heavy metal bromites precipitate as solids. [1]
The classic case is sodium bromide, which fully dissociates in water: NaBr → Na + + Br −. Hydrogen bromide, which is a diatomic molecule, takes on salt-like properties upon contact with water to give an ionic solution called hydrobromic acid. The process is often described simplistically as involving formation of the hydronium salt of bromide:

Sodium hypobromite is an inorganic compound with the chemical formula Na O Br. It is a sodium salt of hypobromous acid. It consists of sodium cations Na + and hypobromite anions − OBr. It is usually obtained as the pentahydrate, so the compound that is usually called sodium hypobromite actually has the formula NaBrO·5H 2 O. It is a yellow ...
Sodium hypobromite can be isolated as an orange solid. A secondary reaction, where hypobromite spontaneously disproportionates to bromide (bromine oxidation state −1) and bromate (bromine oxidation state +5) takes place rapidly at 20 °C and slowly at 0 °C. 3 BrO − → 2 Br − + BrO − 3
