Vedclass · Answer

(B) Phenolphthalein is a weak organic acid with a $pH$ range of $8.2$ to $10.0$. It is suitable for titrations involving a strong base because the equivalence point of such titrations falls within its $pH$ range. In the case of $CH_3COOH$ (weak acid) and $NaOH$ (strong base),the resulting salt undergoes anionic hydrolysis,making the solution basic at the equivalence point $(pH > 7)$. Therefore,phenolphthalein is the appropriate indicator for this titration.

Phenolphthalein is a suitable indicator for the titration of:
