Problem
Phenolphthalein is suitable for a strong-acid–strong-base titration but not for a weak-acid–strong-base titration that has a more gradual pH change near the equivalence point. Describe why selecting an indicator whose color change occurs entirely within the steep region of the titration curve improves accuracy.
