Permanganate color change
WebSolution. KMnO 4: Mn in KMnO 4 is in + 7 state with d 10 configuration. The deep purple color of KMnO 4 is not due to the d - d transition, but because of the charge transfer (from … WebThe "end point" (observable change) should be very close to the equivalence point at which an exactly stoichiometric amount of the known reactant has been added. In the following procedure we will use the deep purple color of the KMnO4 to follow the progress of the reaction. When the permanganate ion reacts with Fe2+ the products are colorless.
