MnO-4 + 5Fe2++8H+ arrow 5Fe3+ + Mn2+ + 4H2O In the above reaction 1 mole of MnO4 reacts with 5 mole of Fe2+. or 1 mole of Fe2+ reacts with 0.2 mole of MnO4-.

Q. The colour of $K M n O_{4}$ solution is decolourised by $F e^{2 +}$ solution, one mole of $F e^{2 +}$ reacts with $x$ moles of $K M n O_{4}$ . Find $x$ .

$M n O_{4}^{-} + 5 F e^{2 +} + 8 H^{+} 5 F e^{3 +} + M n^{2 +} + 4 H_{2} O$
In the above reaction $1$ mole of $M n O_{4}$ reacts with $5$ mole of $F e^{2 +}$ .
or $1$ mole of $F e^{2 +}$ reacts with $0.2$ mole of $M n O_{4}^{-}$ .
