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 a titration lies in the basic range $(pH > 7)$. Among the given options,$CH_3COOH$ is a weak acid and $NaOH$ is a strong base,making phenolphthalein the ideal indicator for this titration.

Phenolphthalein is the most suitable indicator for the titration of:
