Titration curves graph pH versus the volume of titrant added. For acid–base titrations, the equivalence point occurs when moles of acid equal moles of base. The shape of the curve and the pH at equivalence depend on the acid/base strength. Polyprotic acids display multiple equivalence points. Analyzing titration curves helps determine acid dissociation constants (Ka), buffer regions, and the acid or base concentration in the sample.
