1.	When `MnO_(2)` is fused with `KOH,` a coloured compound is formed, the product and its colour is:A. `K_(2)MnO_(4)`, Purple greenB. `KMnO_(4), `PurpleC. `Mn+(2)O_(3)`, BrownD. `Mn_(3)O_(4)` Black
Answer» Correct Answer - A Stable oxidation state of Mn in alkaline medium is `+6` . So, `MnO_(2)` is oxidised to `K_(2)MnO_(4)`(purple green) by atmospheric oxygen in KOH medium. `2MnO_(2) 4KOH+O_(2) rarr 2K_(2)MnO_(4)+2H_(2)O`
