Prove that Potassium permanganate is an oxidising agent in neutral medium.

Answer»

SOLUTION :In neutral medium, `KMnO_(4)` it is reduced to `MnO_(2)`
`MnO_(4)^(-) + 2H_(2)O + 3e^(-) toMnO_(2) + 4OH^(-)`
Example: Potassium PERMANGANATE oxidises `H_(2)S` to SULPHUR in neutral medium.
`2MnO_(4)^(-) + 3H_(2)S to 2MnO_(2) + 3S + 2OH^(-) + 2H_(2)O`
