Vedclass · Answer

(B) Phenolphthalein is a weak organic acid indicator with a pH range of $8.2$ to $10.0$. It is most suitable for titrations involving a strong base and a weak acid,as the equivalence point for such titrations lies in the basic range $(pH > 7)$. In the given options,$CH_3COOH$ is a weak acid and $NaOH$ is a strong base. Therefore,the titration of $CH_3COOH$ and $NaOH$ is best indicated by phenolphthalein.

For which of the following titrations is phenolphthalein the most suitable indicator?
