STRUCTURE OF MNO4-

In strongly alkaline medium, MnO_4^- MnO_4^(-) + e^(-) to MnO_4^(2-) In this medium, equivalent weight of KMnO_4 is reduced as:

MnO_4^- and _______are formed by the disproportionation of MnO_4^(2-) in acidic medium.

Complete the following reactions. (i) MnO_4^(-)+2H_2O+3e^(-)to"_________"+4OH^(-) (ii) MnO_4^(-)+8H^(+)+5e^(-)to "__________" +4H_2O (iii) MnO_4^(-)+e^(-)to "_________"
