Phosphorus occurs naturally at low levels in water, plants, and animals. Oxide - Oxide - Oxides of phosphorus: Phosphorus forms two common oxides, phosphorus(III) oxide (or tetraphosphorus hexoxide), P4O6, and phosphorus(V) oxide (or tetraphosphorus decaoxide), P4O10. The interesting thing about diphosphorus pentoxide ##P_2O_5## is that it usually exists as a dimer. SPECIFICATION PROPERTIES Phosphorus pentoxide is the anhydride of orthophosphoric acid, H3PO4. The safest method is to dry in a vacuum desiccator over concentrated sulphuric acid, phosphorus pentoxide, silica gel, calcium chloride, or some other desiccant. Oxyhalides of phosphorus are also produced when the pentoxide is heated with fluorides or chlorides of the alkali and alkaline earth metals; thus POF 3 is produced with calcium fluoride and POCl 3 with sodium chloride. Inhalation: Inhalation produces damaging effects on the mucous membranes and upper respiratory tract. This implies that ##P_2O_5## is actually the compound’s and that you should use ##P_4O_10## as its molecular formula. This white crystalline solid is the anhydride of phosphoric acid.
