An old chesnut...
Explanation:
Oxidations by permanganate ion are particularly useful inasmuch as the oxidized form
And nitrite,
And so we take TWO of the former equations, and FIVE of the latter to eliminate the electrons, virtual particles of convenience...
And we cancel away....
The which is balanced with respect to mass and charge...as is ABSOLUTELY required... Capisce? Of course the sulfate ions, and the potassium ions are along for the ride, and these are not involved in the redox process. If you like you can add the gegenions as an exercise...
