Phosphoric Acid

Our provided Phosphoric Acid is a phosphorus-containing inorganic acid made up of phosphorus, oxygen, and hydrogen. In a broardened term, it includes the monomeric (orthophosphoric acid), dimeric (pyrophosphoric acid), and polymeric (metaphosphoric acid) forms of the acid. Phosphoric acid commonly indicates the monomeric form orthophosphoric acid. On heating to about 225 C, it dehydrates to form pyrophosphoric acid and to metaphosphoric acid (2HPO3 = P2O5.H2O) at higher temperatures. Pyrophosphates are salts of pyrophosphoric acid and metaphosphates are salts of metaphosphoric acid. Two molecules of orthophosphoric acid are formed when three molecules of water are added to one molecule of phosphorus pentoxide (2H3PO4 = P2O5.3H2O). The pyrophosphates are formed by the loss of 1 molecule of water from 2 moles of an orthophosphate. Pure orthophosphoric acid is a crystalline solid; melting point 42 C; soluble in alcohol, and very soluble in water. Phosphoric Acid violently polymerizes under the influence of azo compounds, epoxides and other polymerizable compounds. It forms toxic fumes of phosphorous oxides when combusted. It is a medium strong acid and attacks metals to release flammable hydrogen gas. Decomposition may occur on contacting with alcohols, aldehydes, cyanides, ketones, phenols, esters, sulfides, halogenated organics compounds.
