Titration curves

At the end of this activity, students should be able to:
– describe how the pH of a solution changes upon gradual addition of the titrant
– describe the characteristics of pH curves for strong acid–strong base, weak acid–strong base and weak base–strong acid titrations
– explain how indicators work
– choose the appropriate indicator for a given titration
– discuss qualitatively pH curves with two equivalence points
– indicate the limitations of acid–base titrations.
