It is a colourless, water-sensitive and moisture-sensitive solid, although commercial samples can be yellowish and contaminated with hydrogen chloride 5 years ago. Phosphorus pentoxide was used in the early and mid-20 th century to procure phosphoric acid, by dissolving the former in water. Phosphorus pentoxide is employed as a dehydrating agent in reactions that require removal of water molecules (e.g. It is even capable of robbing water from sulfuric acid, allowing one to distill sulfur trioxide from it. allotropes of phosphorus Phosphorus occurs in several allotropic forms, the most common of which are white phosphorus and red phosphorus (Fig 2). ( Two identical molecules linked together) P4O10 -Molecular formula. The reaction with water is very vigorous and proceeds with the evolution of a large … Now diphosphorus pentoxide reacts violently with water to … Phosphorous pentoxide is an inorganic chemical compound, composed of four phosphorus atoms and ten oxygen atoms. It reacts with water to form phosphoric acid H3PO4. 1314-56-3 . It is very hygroscopic and is converted by water to H3PO4 via intermediates. This implies that ##P_2O_5## is actually the compound’s and that you should use ##P_4O_10## as its molecular formula. Removal of water. But this required a supply of white phosphorus, which is comparatively hard to find. This compound crystallizes in four different polymorphs. International Chemical Safety Card van Difosforpentoxide (en) Website of the Technische Universität Darmstadt and the CEEP about Phosphorus Recovery Its chemical name is tetraphosphorous decaoxide.

View information & documentation regarding Phosphorus pentoxide, including CAS, MSDS & more. Phosphorus is burned to make phosphorus pentoxide [phosphorus(V) oxide], a white solid used as a chlorinating agent in organic chemistry, as a drying agent and mainly converted to phosphoric acid used to make phosphates for fertilizers, electro chemical polishing and shaping, electroplating, metal cleaning and pickling in metal treatment by reaction with water. This generates fire and explosion hazard. Inhalation: Inhalation produces damaging effects on the mucous membranes and upper respiratory tract. That enables it to remove free water molecules by a simple hydrolysis reaction, but here of course there must be some other electron movement since the water being removed is not free water. Phosphorus pentoxide reacts with moisture on body tissue surfaces to form phosphoric acid, which approximates sulfuric acid and hydrochloric acids in corrosive intensity. Phosphorus pentoxide (P 4 O 10) is a white powder and very deliquescent (forming phosphoric acid), and is used as a dehydrating agent. It exists as a dimer.
