AI Thread Summary
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.

Sulphuric acid is a diprotic acid that dissociates completely when dissolved in water. How does a monoprotic acid like trifluoromethanesulfonic acid produce a greater pH change than H2SO4?

Sulfuric acid is a diprotic acid that DOESN'T dissociate completely in water. 0.01M solution is about 50/50 SO42- and HSO4-.

How does a monoprotic acid like trifluoromethanesulfonic acid produce a greater pH change than H2SO4?

Does it?
