Pure product is yellow crystals. Industrial product is mostly lemon yellow alkaline solution. It is easily 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 |
