Explain the indicator electrode at the equivalence point

Reference no: EM13524256

KMnO4 is used as the tirant in a potentiometric titration of tin(II) to tin(IV), using a S.C.E. reference electrode. The potential of the indicator electrode at the equivalence point would be calculated as:

(a) 7 E+ = 5 Eo(MnO4-/Mn2+) + 2 Eo(Sn4+/Sn2+).

(b) 7 E+ = 2 Eo(MnO4-/Mn2+) + 5 Eo(Sn4+/Sn2+):
