WebPhosphoric acids and phosphates Pyrophosphoric acid. A phosphoric acid, in the general sense, is a phosphorus oxoacid in which each phosphorus (P) atom is in the oxidation state +5, and is bonded to four oxygen (O) atoms, one of them through a double bond, arranged as the corners of a tetrahedron. Two or more of these PO Phosphorus pentoxide is a potent dehydrating agent as indicated by the exothermic nature of its hydrolysis producing phosphoric acid: P4O10 + 6 H2O → 4 H3PO4 (–177 kJ) However, its utility for drying is limited somewhat by its tendency to form a protective viscous coating that inhibits further dehydration by … See more Phosphorus pentoxide is a chemical compound with molecular formula P4O10 (with its common name derived from its empirical formula, P2O5). This white crystalline solid is the anhydride of phosphoric acid. … See more P4O10 is prepared by burning white phosphorus with a sufficient supply of oxygen: P4 + 5 O2 → P4O10 The dehydration of phosphoric acid to give phosphorus pentoxide is not possible, as on heating it forms … See more Phosphorus pentoxide itself is not flammable. Just like sulfur trioxide, it reacts vigorously with water and water-containing substances like wood or cotton, liberates much heat … See more Phosphorus pentoxide crystallizes in at least four forms or polymorphs. The most familiar one, a metastable form (shown in the figure), comprises molecules of P4O10. Weak van der Waals forces hold these molecules together in a hexagonal lattice (However, in … See more Between the commercially important P4O6 and P4O10, phosphorus oxides are known with intermediate structures. On observation it … See more • Eaton's reagent See more
