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)'M nO_(2), Mn^(2+)`
B. `MnO_(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 natural medium,
`2KMnO_(4)+3MnSO_(4)+2H_(2)OtoK_(2)SO_(4)+ 2H_(2)SO_(4) + 5M nO_(2)`
In alkaline medium,
`2KMnO_(4)+ H_(2)Oto 2MnO_(2)+ 2KOH+3O`
In acidic medium,
`2KMnO_(4) +3H_(2)SO_(4) to K_(2) SO_(4) +overset(+2)(2MnSO_(4))+5H_(5)O+5O`
