Phosphoric acid - Wikipedia

Phosphoric acid, H 3 PO 4, is a tribasic acid.The speciation diagram shows that, in aqueous solution, there are five main pH regions. There are 3 regions, centred where the pH is equal to a pK value, which are buffer regions.; In the region centred around pH 4.7 (mid-way between the first two pK values) the dihydrogen phosphate ion, [H 2 PO 4] −, is the only species present.
