Potassium permanganate acts as an oxidant in neutral, alkaline as well as acidic medium. The final products obtained from it in the three conditions are, respectively

Options

A. `MnO_(2+), MnO_2, Mn^(2+)`
B. `MnO_4^(2-), MnO^(3+), Mn^(2+)`
C. `MnO_(2+), MnO_4^(2-), Mn^(3+)`
D. `MnO, MnO_4^(2-), Mn^(2+)`

Answer

A

Explanation

`" In neutral medium: " 2KMnO_4 + 3MnSO_4 + 2H_2O rarr K_2SO_4 + 2H_2SO_4 + 5MnO_2`
`" In alkaline medium: " 2KMnO_4+H_2O rarr 2MnO_2 + 2KOH + 2O`
`"In acidic medium: " 2 KMnO_4 + 3H_2SO_4 rarr K_2SO_4 + 2Mn^(+2)SO_4 + 5H_2O + 5O`
