| Hazard Information | Back Directory | [Description]
Barium phosphite can have the molecular formula of
BaHPO3 or Ba(H2PO3)2 with molecular weights of
216.3021 and 296.2739 g/mol, respectively. It is the latter
that appears when a solution of phosphorous acid is
reacted with the carbonate:
BaCO3 +H3PO3 ? Ba(H2PO3)2 +H2O + CO2 | [Preparation]
Barium phosphite is soluble in water so that a vacuum
evaporation is needed to form the hemihydrate, Ba(H2-
PO3)2·0.5H2O. It can also be prepared by the action of
ammonium phosphite on barium chloride:
BaCl2 (aq) + 2NH4HPO3 (aq) ? Ba(H2PO3)2·0.5H2O
+ 2NH4Cl (aq). |
