Question

Molecular weight of KMnO4 is is "M". in reaction KMnO4 is reduced to K2MnO4. the equivalent weight of KMnO4​

Answer 1

Answer:

Only 1 electron is gained by permanganate ion to convert to manganate ion. We can also see that the oxidation state of manganese is +7 in permanaganate ion and it changes to +6 in manganate ion. That is, the oxidation state changes by 1. Hence, the equivalent mass of KMnO4 is M when it converts over to K2MnO4
