Vedclass · Answer

(B) The correct answer is $(B)$.Phenolphthalein is an acid-base indicator used for titrations involving strong bases and weak acids or strong bases and strong acids.However,in the titration of ferrous sulphate $(FeSO_4)$ against potassium permanganate $(KMnO_4)$,the reaction is a redox titration.$KMnO_4$ acts as a strong oxidizing agent and it oxidizes the phenolphthalein indicator,causing it to lose its characteristic color-changing property,making it unsuitable for this specific titration.
