Permanganate ion is reduced to #MnO_2#, and ammonia is oxidized to nitrate ion. Can you write a balanced chemical equation to represent the redox process?
This is a good one...............
You really have to make a meal out of these redox equations.
Permanganate ion (STRONGLY COLOURED PURPLE) could be reduced to almost colourless
But here it is reduced to
Ammonia is OXIDIZED to nitrate anion.......(there is no associated colour change; ammonia pen and inks very badly, whereas ammonium ion/salt is odourless, but I do not suggest you use this method to differentiate them!)
Now if I have done my sums right;
And we cancel out common reagents to give (finally!):
Even despite the whack coefficients this is stoichiometrically balanced AS IS ABSOLUTELY REQUIRED...........
But you specified the reduction of permanganate to
But I note (well eventually I did!) that you specified BASIC conditions; all I have to do is add
