Phosphoric acid (orthophosphoric acid, monophosphoric acid or phosphoric(V) acid) is a colorless, odorless phosphorus-containing solid, and inorganic compound with the chemical formula H3PO4. It is commonly encountered as an 85% aqueous solution, which is a colourless, odourless, and non-volatile syrupy … See more Phosphoric acid is produced industrially by one of two routes, wet processes and dry. Wet process In the wet process, a phosphate-containing mineral such as calcium hydroxyapatite See more Acidic properties In aqueous solution phosphoric acid behaves as a triprotic acid. H3PO4 ⇌ H2PO−4 + H , pKa1 = 2.14 H2PO−4 ⇌ HPO2−4 + H , pKa2 = 7.20 HPO2−4 ⇌ PO3−4 + H , pKa3 = 12.37 The difference … See more Phosphoric acid is not a strong acid.
