WebWeak acid titration In this experiment you will titrate H3PO4 with a dilute solution of NaOH. H3PO4 is phosphoric acid. It is the major acid that gives cola its acidity. It is a triprotic weak acid, which means contains three acidic protons. Therefore, it has three acid dissociation constants; Ka1 = 7.11⋅10-3, K a2 = 6.34⋅10-8 and K a3 = 8 ...
