The oxidation number of Mn in the product of alkaline oxidative fusion of `MnO_(2)` is

Text Solution

Verified by Experts

The correct Answer is:
6
`2MnO_(2) + 4KOH+O_(2) overset("fusion")(rarr)2K_(2)MnO_(4)+2H_(2)O`
Let the oxidation state to `Mn` in `MnO_(4)^(2-)` is x.
So, `x+4(-2)=-2` or `x=6`.
