Equivalent mass of KMnO_(4) in acidic medium, concentrated alkaline me

1.	Equivalent mass of KMnO_(4) in acidic medium, concentrated alkaline medium and dilute basic medium respectively are M, M, M. Reduced products can be
Answer» `MnO_(2), MnO_(4)^(-) , Mn^(2+)` `MnO_(2), Mn^(2+), MnO_(4)^(2-)` `Mn^(2+), MnO_(2), MnO_(4)^(2-)` `Mn^(2+), MnO_(4)^(2-), MnO_(2)` SOLUTION :`MnO_(4)^(-) + 8H^(+) + 5e^(-) to Mn^(2+) + 4H_(2)O`(acidic medium) `MnO_(4)^(-) + 4H^(+) + 3e^(-) to MnO_(2) + 2H_(2)O`(CONCENTRATED basic medium) `MnO_(4)^(-) + e^(-) to MnO_(4)^(2-)`(DILUTE basic medium)
