Both oxides have a structure based on the tetrahedral structure of elemental white phosphorus. This reaction is highly exothermic. When heated above 210°C, phosphorus trioxide dissociates into PO 2 and red phosphorus. Phosphorus(V) oxide reacts violently with water to give a solution containing a mixture of acids, the nature of which depends on the conditions. Inhalation: Inhalation produces damaging effects on the mucous membranes and upper respiratory tract. Phosphorus pentoxide is the anhydride of phosphoric acid. The reaction produces phosphoric acid. Find another reaction. Phosphorus pentoxide is employed as a dehydrating agent in reactions that require removal of water molecules (e.g. The combination of phosphorus and carbon shows thermal inertia. Phosphorus pentoxide is the anhydride of orthophosphoric acid, H3PO4. Phosphorus pentoxide is also a very potent dehydrating agent. Reacts violently with perchloric acid. Phosphorus Pentoxide is a chemical compound with molecular formula P 4 O 10 (with its common name derived from its empirical formula P 2 O 5). Its chemical name is tetraphosphorous decaoxide. 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.
