The most prevalent compounds of phosphorus are derivatives of phosphate (PO4 ), a tetrahedral anion. Phosphate is the conjugate base of phosphoric acid, which is produced on a massive scale for use in fertilisers. Being triprotic, phosphoric acid converts stepwise to three conjugate bases: H3PO4 + H2O ⇌ H3O + H2PO4 Ka1 = 7.25×10
