Lithium bromite, LiBrO2, is formally the lithium salt of bromous acid. It is prepared by the controlled disproportionation of lithium hypobromite at pH 11–12 and 0 °C.[1][2] The anhydrous salt can be prepared by heating lithium bromate with lithium bromide at 190 °C.[3]
- 2 LiBrO3 + LiBr → 3 LiBrO2
