Phosphorus Pentoxide

Phosphorus Pentoxide

Phosphorus pentoxide is a chemical compound with formula P2O5. This white crystalline solid is the anhydride of phosphoric acid. It is a powerful desiccant. This is a white, flammable, dangerous, and extremely deliquescent solid. The solid reacts with water violently to produce phosphoric acid. It is prepared by phosphorus reaction with excess oxygen. The crude is then purified by sublimation. Phosphorus pentoxide is Stable, but reacts violently with water, alcohols, metals, sodium, potassium, ammonia, oxidizing agents, HF, peroxides, magnesium, strong bases.

Synonyms: phosphoric anhydride, diphosphorus pentaoxide, Phosphorus oxide, phosphoric pentoxide, phosphorous a nhydride, phosphorous pentaoxide.
