Explain the preparation of potassium permanganate from MnO_(2) Write the balanced chemical equations for the reactions involved. |
|
Answer» Solution :Potassium PERMANGANATE is prepared by the fusion of `MnO_(2)`with an alkali METAL hydroxide and an OXIDISINGAGENT like `KNO_(3)`. This RESULTS in the formation of the dark green `K_(2)MnO_(4)`which disproportionates in a neutral or acidic solution to give potassium permanganate. `2MnO_(2) +4KOH +O_(2)to 2K_(2)MnO_(4) +2H_(2)O` `3K_(2)MnO_(4) +4H^(+)to 2KMnO_(4) +MnO_(2) +2H_(2)O +4K^(+)` |
