Phosphoric acid (orthophosphoric acid, monophosphoric acid or phosphoric(V) acid) is a colorless, odorless phosphorus-containing solid, and inorganic compound with the chemical formula . It is commonly encountered as an 85% aqueous solution, which is a colourless, odourless, and non-volatile syrupy liquid. It is a major industrial chemical, being a component of many fertilizers.
The compound is an acid. Removal of all three ions gives the phosphate ion . Removal of one or two protons gives dihydrogen phosphate ion and the hydrogen phosphate ion respectively. Phosphoric acid forms esters, called organophosphates.
The name &quot;orthophosphoric acid&quot; can be used to distinguish this specific acid from other &quot;phosphoric acids&quot;, such as pyrophosphoric acid. Nevertheless, the term &quot;phosphoric acid&quot; often means this specific compound; and that is the current IUPAC nomenclature.
