Phorphoric acid is an acidifier because it donates H+ protons to other atoms around it, making it a protonator. This protonation process shows HOW phosphoric acid is a catalyst. Phosphoric acid is an acid catalyst. It transfers protons for processes such as esterification. Note that aspirin itself is an ester.
