We usually just consider one of these, phosphoric(V) acid, H 3 PO 4 - also known just as phosphoric acid or as orthophosphoric acid. As a new method of forming phosphoric acid was discovered, this method fell out of fashion. View information & documentation regarding Phosphorus pentoxide, including CAS, MSDS & more. It is even capable of robbing water from sulfuric acid, allowing one to distill sulfur trioxide from it. It is also used as starting material for phosphate esters (used as extraction agents and surfactants) and reagent for polymerization reaction and organic synthesis. Oxyhalides of phosphorus are also produced when the pentoxide is heated with fluorides or chlorides of the alkali and alkaline earth metals; thus POF 3 is produced with calcium fluoride and POCl 3 with sodium chloride. Both oxides have a structure based on the tetrahedral structure of elemental white phosphorus. This implies that ##P_2O_5## is actually the compound’s and that you should use ##P_4O_10## as its molecular formula. Phosphorus, white, dry or under water or in solution appears as a soft waxy solid with a sharp pungent odor similar to garlic. *Please select more than one item to compare Compare Products: Select up to 4 products. It is a powerful desiccant and dehydrating agent. Phosphorus(V) oxide reacts violently with water to give a solution containing a mixture of acids, the nature of which depends on the conditions. Its chemical name is tetraphosphorous decaoxide. It is generally found as a dimer of P 2 O 5 that’s why it is known as phosphorous pentoxide. As with most materials in contact with the atmosphere, even at moderate humidities, hemihydrate a d sorbs something approaching a monolayer of water, but reaction cannot occur because this water cannot hold anything in solution. It is a colourless, water-sensitive and moisture-sensitive solid, although commercial samples can be yellowish and contaminated with hydrogen chloride Phosphorus pentachloride is the chemical compound with the formula PCl 5.It is one of the most important phosphorus chlorides, others being PCl 3 and POCl 3.PCl 5 finds use as a chlorinating reagent.
