Monoprotic acids, such as trifluoromethanesulfonic acid (TFMSA), can produce a greater pH change than diprotic acids like sulfuric acid (H2SO4) under certain conditions. While sulfuric acid is a diprotic acid that partially dissociates in a 0.01M solution, resulting in a mixture of sulfate (SO42-) and hydrogen sulfate (HSO4-), TFMSA, being a strong monoprotic acid, fully dissociates, leading to a more significant pH shift. This discussion highlights the importance of understanding the dissociation behavior of different acid types in aqueous solutions.
PREREQUISITESChemistry students, educators, and professionals interested in acid-base reactions, particularly those focusing on the comparative analysis of monoprotic and diprotic acids.
BogMonkey said: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?
