Sodium bromite

Chemical Properties

Pure product is yellow crystal. Industrial products are mostly lemon yellow alkaline solution. Soluble in water.

Uses

NaBrO2

Uses

Sodiumbromite is used in preparation method of high-purity sodium bromite aqueous solution.

Preparation

Bromous acid can thus be produced by a classical chemical or an electrochemical method in which hypobromite is oxidized to the bromite anion:
HBrO＋ HClO→HBrO2＋ HCl or HBrO＋ H2O＋ e^- →HBrO2＋ H2
Also disproportioning of hypobromous acid will give bromous acid and hydrobromic acid:
2HBrO＋ heat→HBrO2＋ HBr
In addition, a rearrangement reaction of bromic acid and hydrobromic acid will produce bromous acid:
2HBrO3＋ HBr→3HBrO2
