Sodium bromite, NaBrO2, is formally the sodium salt of bromous acid. It is prepared by the controlled disproportionation of sodium hypobromite at pH 11–12 and 0 °C, and is commercially available as a 10% aqueous solution or as a solid trihydrate.[1] It is used as a desizing agent in the textile industry.[1][2]
