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:

`MnO_(2), MnO_(2), Mn^(2+ )`

`MnO_(4)^(2-), Mn^(3+), Mn^(2+)`

`Mn_(2), MnO_(4)^(2-), Mn^(3 +)`

`Mn, MnO_(4), Mn^(3 +)`

Text Solution

Verified by Experts

The correct Answer is:

`MnO_(2), MnO_(2), Mn^(+2)`
In neutral medium:
`2KMnO_(4) + MnSO_(4) + 2H_(2)O rarr K_(2)SO_(4) + 2H_(2)SO_(4) + 5MnO_(2)`
In alkaline medium:
`2KMnO_(4) + H_(2)O rarr 2MnO_(4) + 2KOH + 30`
acidic medium:
`2KMnO_(4) + 3H_(2)SO_(4) rarr K_(2) SO_(4) 2CrO_(5) + %H_(2) O`
