| Description | Barium peroxyphosphate has remained unknown
and little to no publications concerning this salt are
available on the scientific literature. Like the other alkaline
earths, Barium peroxyphosphates could be
prepared by both solid-state or solution methods. The
two sets of compounds would likely differ. For the
monoperoxyphosphates, one would get BaHPO5 for
the former method and perhaps a hydrate for an
aqueous solution. The question of degree of hydration
remains unknown.
In the solution method, one could use either the acid,
H3PO5 or the potassium salt K2HPO5. Whether the solution
should be acidic or basic is not known. Like the other
alkaline earths, it is probably best to prepare the acid in
a nonaqueous solution like carbon tetrachloride and
then add the potassium compound for the basic solution:
P2O5 + 2H2O2 +H2O ? 2H3PO5
2H3PO5 + KOH ? K2HPO5
To either of these is added a barium compound to
form the monoperoxyphosphate:
Ba(OH)2 + K2PO5 ? BaHPO5 +H2O
For the diperoxy compounds, the potassium monoperoxyphosphate
compound is transformed to the diperoxyphosphate
compound, in a nonaqueous solution at
low temperature:
K2HPO5 + P2O5 ? K2P2O8
For barium, the probable compounds that will be
formed are:
BaHPO5
Ba2P2O8
Other possible compounds are:
Ba(H2PO5)2
Ba(H2P2O8)2 |
