KMnO4 is used as the titrant in a potentiometric titration of tin(II) to tin(IV), using a S.C.E. reference electrode. After the equivalence point, you would calculate the cell voltage using the potentials of:
a) the MnO4- / Mn2+ couple and the S.C.E.
b) the Sn4+ / Sn2+ couple and the S.C.E.
c) the MnO4- / Mn2+ couple and the Sn4+ / Sn2+ couple.
