WebNov 15, 2013 · The N-P-K ratings found on fertilizer labels can be confusing and misleading. They indicate the minimum guaranteed amounts of nitrogen (N), phosphorus oxide (P2O5), and potassium oxide (K2O). However, these numbers don't accurately represent the elemental parts per million (ppm) of the primary elements. For instance, a 30-10-10 … 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 … 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 P4O10 is prepared by burning white phosphorus with a sufficient supply of oxygen: P4 + 5 O2 → P4O10 The dehydration of See more Between the commercially important P4O6 and P4O10, phosphorus oxides are known with intermediate structures. On observation it will be seen that double bonded oxygen in at 1,2 position or 1,3 position are identical and both positions have same steric … See more • Eaton's reagent See more
