One common method involves the combustion of phosphorus in the presence of excess oxygen. This reaction produces phosphorus pentoxide as a white solid residue. The equation for this process is P4 + 5O2 → 2P2O5.

Apr 9, 2024 · white monoclinic crystals or powders. Relative density 2. 30 I melting point 340 ℃,360℃ sublimation. Soluble in sulfuric acid, insoluble in ammonia and acetone. Contact with water to generate phosphoric acid and release a large amount of heat, and organic matter will burn. Corrosive to the skin. Exposure to organic matter may cause combustion risk.

Mar 18, 2014 · Phosphorus pentoxide is a white, microcrystalline, light weight powder which is produced by the combustion of elemental phosphorus in an excess of oxygen. Phosphorus pentoxide is the anhydride of orthophosphoric acid, H3PO4. It is very hygroscopic and is converted by water to H3PO4 via intermediates.
