Vedclass · Answer

(C) Phenolphthalein is an acid-base indicator that changes color in the $pH$ range of $8.2$ to $10.0$. It is suitable for titrations involving strong bases. Option $C$ involves $KMnO_4$,which is an oxidizing agent,not a simple acid-base titration. Furthermore,$KMnO_4$ acts as a self-indicator in redox titrations,making the use of phenolphthalein unnecessary and inappropriate for this specific reaction.

Phenolphthalein is not a suitable indicator for the titration between which of the following?
