http://www.titrations.info/acid-base-titration-phosphoric-acid WebKey features of titration curves: Equivalents: the x-axis scale for titrations is given in moles of base/moles of acid. Therefore, it varies from 0 to 1 for an acid that releases one proton (monoprotic), from 0 to 2 for a diprotic acid, 0 to 3 for a triprotic acid. ... Using the phosphate titration as an example, the last ionization begins at ...
