$FeSO_4 \, vs. \, KMnO_4$

Vedclass · Answer

(B) Phenolphthalein is an acid-base indicator used to detect the equivalence point in acid-base titrations. $FeSO_4 \, vs. \, KMnO_4$ is a redox titration,not an acid-base titration. In a redox titration,the change in potential is monitored,and phenolphthalein does not change color based on the oxidation-reduction state of the reactants. Therefore,it is not a suitable indicator for this reaction.
