Answer 2

Explanation:

Phenolphthalein is a chemical compound with the formula C20H14O4 and is often written as "HIn" or "phph" in shorthand notation.Phenolphthalein is often used as an indicator in acid–base titrations. For this application, it turns colorless in acidic solutions and pink in basic solutions.

Again phenolphthalein is a good choice. For a titration of a strong acid against a weak base, the titration curve is steepest a little below pH = 7, and many not be as steep at the range wherephenolphthalein changes colour. So it is not agood choice.
