underset1 molFe2(C2O3) leftharpoons 2Fe3+ + underset3 mol3C2O42- Only C 2 O 42- oxidised 2 MnO 4-+5 C 2 O 42- arrow 10 CO 2+2 Mn 2+ 5 mol C 2 O 42- ≡ 2 mol MnO 4- ∴ 3 mol C 2 O 42-=1.2 mol MnO 4-

Q. $1$ mole of ferric oxalate is oxidized by $x$ moles of $M n O_{4}^{-}$ .Thus, $x$ is

$1.2$

$2.1$

$3.1$

$1.3$

$1 m o l F e_{2} (C_{2} O_{3}) ⇌ 2 F e^{3 +} + 3 m o l 3 C_{2} O_{4}^{2 -}$
Only $C_{2} O_{4}^{2 -}$ oxidised
$2 M n O_{4}^{-} + 5 C_{2} O_{4}^{2 -} \to 10 C O_{2} + 2 M n^{2 +}$
$5 m o l C_{2} O_{4}^{2 -} \equiv 2 m o l M n O_{4}^{-}$
$∴ 3 m o l C_{2} O_{4}^{2 -} = 1.2 m o l M n O_{4}^{-}$
