Potassium permanganate acts as an oxidant in neutral, alkaline as well as acidic media. The final product obtained from it in three condition are respectively:

Options

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

Answer

A

Explanation

`MnO_2, MnO_2, Mn^(2+)`
In neutral medium,
`2KMnO_4 + 3MnSO_4 + 2H_2O to K_2SO_4 + 2H_2SO_4 + 5MnO_2`
In alkaline medium,
`2KMnO_4 + H_2O to 2MnO_4 + 2KOH + 3O`
In acidic medium,
`2 KMnO_4 + 3H_2SO_4 to K_2SO_4 + 2overset(+2)MnSO_4 + 5H_2O + 5O`
