Aqueous H3PO4 polyprotic in nature which means more than one protons can be donated. The pKa value measures the acidity of a solution based on how the hydrogen ions of the acid dissociate when added to an aqueous solution. Since phosphoric acid, represented by the molecular formula H3PO4, has three hydrogen atoms, it dissociates three times, into H 2 PO 4 –, HPO 4 2-and PO 4 3-.The pKa value is based on the Ka value, which is called the acid dissociation constant.
