Abstract
Titration curves and choosing indicators.
Concept preview
What you will be able to do
- 01Interpret a titration curve
- 02Relate the half-equivalence point to pKa
- 03Choose an appropriate indicator for a titration
Plotting the pH of the solution against the volume of titrant added produces a titration curve. Its characteristic shape is a gentle change at first, then a steep, almost vertical jump over the addition of just a drop or two near the equivalence point, and finally a gentle levelling off. The steep region is the signature of the equivalence point, and the midpoint of that vertical jump marks it precisely.
