Sulfuric acid is identified as a diprotic acid that does not fully dissociate in dilute solutions, such as a 0.01M concentration, where it exists in roughly equal parts as sulfate (SO42-) and hydrogen sulfate (HSO4-). The discussion raises the question of how a monoprotic acid, specifically trifluoromethanesulfonic acid, can induce a greater pH change compared to sulfuric acid. This prompts further inquiry into the dissociation behavior and strength of these acids, suggesting that the pH impact may not solely depend on the number of protons an acid can donate.
