Abstract
Bismuth(V) as sodium bismuthate, NaBiO3, is quantitativelyreduced to bismuth(III) in aqueous hydrofluoric acid at theexpense of water oxidation. NaBiO3, with aqueous hydrofluoricacid and a solution of ammonium fluoride in aqueous hydrofluoricacid, gave trifluorobismuth(III) monohydrate, BiF3.H2O, andammonium tetrafluorobismuthate(III), NH4BiF4, respectively.BiF3.H2O undergoes dehydrofluoridation (-2HF) at 350-400°C inthe presence of air to produce BiOF. The results of chemicalanalyses and infrared and laser Raman studies have been used tocharacterise the compounds.
