Suggest why KMnO4 is used in titration and not another oxidizing reagent such as potassium dichromate.

Answer 1

Actually, both KMnO₄ and K₂Cr₂O₇ are routinely used as oxidizing agents in many titrations. KMnO₄ may be preferred in certain circumstances because it is a considerably stronger oxidizing agent than K₂Cr₂O₇.
