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. It is a powerful desiccant and dehydrating agent. 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 … See more 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 … See more Phosphorus pentoxide itself is not flammable. Just like sulfur trioxide, it reacts vigorously with water and water-containing … 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 Between the commercially important P4O6 and P4O10, phosphorus oxides are known with intermediate structures.
