WebPhosphate 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: H 3 PO 4 + H 2 O ⇌ H 3 O + + H 2 PO 4− Ka1 = 7.25×10 −3 H 2 PO 4− + H 2 O ⇌ H 3 O + + HPO 42− Ka2 = 6.31×10 −8 WebPhosphorus is an essential element for plant and animal nutrition. Most phosphorus is consumed as a principal component of nitrogen-phosphorus-potassium fertilizers used on food crops throughout the world. Phosphate rock minerals are the only significant global resources of phosphorus.
