Metaphosphoric acid, HP0 3, is a monobasic acid which may be regarded as derived from orthophosphoric acid by the abstraction of one molecule of water, thus H 3 PO 4 - H 2 O = HP0 3; its constitution is therefore (HO)P0 2.
The acid is formed by dissolving phosphorus pentoxide in cold water, or by strongly heating orthophosphoric acid.
It combines violently with sulphur at 160Ã‚° to form phosphorus sulphoxide, P406S4, which forms highly lustrous tetragonal plates (after sublimation), melting at 102Ã‚° and boiling at 295Ã‚°; it is decomposed by water .into sulphuretted hydrogen and metaphosphoric acid, the latter changing on standing into orthophosphoric acid.
