Equivalent weight of bayer's reagent

Answer»

We know that in BASIC medium KMNO4 (MN oxidation state=7)converts into MnO2 (Mn oxidation state=4) so change in oxidation is 3.

Equivalent weight = MOLECULAR weight÷change in oxidation state

Molecular mass of KMnO4=158

Equivalent weight of KMnO4=158÷3=52.66
