22.5 ml of 0.102N KMnO4 is required to oxidized 10ml. mohr's salt solution,determination the amount of Fe++ of that solution??

Approx...
Explanation:
This is a redox titration...permanganate is reduced to
The colour change allows us to vizualize the stoichiometric endpoint of the reaction...
And
We add FIVE of the latter to ONE of the former....
And so ONE EQUIV of permanganate oxidized FIVE EQUIV of ferrous ion....
And so there are FIVE equiv of ferrous ion present....in a solution whose volume is
