• Phosphorus Pentoxide is a chemical compound whose empirical formula is P2O5 and whose molecular formula is P4O10. Phosphorus pentoxide is an acid anhydride that is obtained from phosphoric acid. It is highly hygroscopic and is, therefore, used as a dehydrating agent and as a desiccant.


  • P2O5 stands for Phosphorus Pentoxide (chemistry)

    Additionally, what is the use of p2o5? Phosphorus Pentoxide Uses. Phosphorus Pentoxide is used as a strong drying and dehydrating agent. Many reactions that require the removal of a water molecule can utilize P2O5 such as the dehydration of amides to nitriles.

    In this way, how is p2o5 formed?

    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.

    Is p2o5 a gas?

    Solid phosphorus reacts with gaseous oxygen to produce solid diphosphorus pentaoxide. Solutions of iron(II) sulfide and hydrochloric acid react to form gaseous hydrosulfuric acid and a solution of iron(II) chloride. Methanol burns in oxygen to produce carbon dioxide gas and water vapor.
