Number of electron transferred in each case when potassium permanganate acts as oxidizing agent give MnO2, Mn²+ Mn(OH) 3 and MnO4²-?
Well you have to write the individual reduction half equations.....
Permanganate ion is reduced to a lower oxidation state manganese ion, and the deep red colour of permanganate dissipates to give a green colour in the case of manganate ion, a brown solid in the the case of the neutral oxide, or colourless in the case of
This normally occurs in basic conditions so we add
And again we add
Are charge and mass balanced in each scenario? All care taken, but no responsibility admitted.
