Synonyms: Metaphosphoric acid

Cas No. 37267-86-0

Description: 

Meta-phosphoric acid (MPA) is a chemical compound . It is a form of phosphorus acid and is part of a series of phosphoric acids, which also includes ortho-phosphoric acid (H₃PO₄) and pyro-phosphoric acid (H₄P₂O₇). It’s generally prepared by heating ortho-phosphoric acid, leading to the loss of water.

1. Structure and Composition: Meta-phosphoric acid is a molecular polymer of phosphorus and oxygen with the empirical formula HPO₃. It consists of a single phosphorus atom bonded to three oxygen atoms, with one hydrogen atom attached to one of the oxygens.
2. Properties:
   • MPA is a relatively strong acid, although it is less commonly encountered compared to ortho-phosphoric acid.
   • It is typically found as a white, crystalline solid.
   • It is hygroscopic, meaning it absorbs water from the air, and is soluble in water, where it dissociates into H⁺ and HPO₃²⁻ ions.
