How many moles of

KMn{O}_{4}

will be needed to react completely with one mole of ferrous oxalate

( Fe{C}_{2}{O}_{4} )

in acidic solution?

Options

A $\dfrac{2}{5}$
B $\dfrac{1}{5}$
C $\dfrac{3}{5}$
D $\dfrac{2}{3}$

Correct answer

C. $\dfrac{3}{5}$

Step-by-step solution

3Mn{O}_{4}^{-} + 5Fe{C}_{2}{O}_{4} + 24H^{+} \to 3Mn^{2 +} + 5Fe^{3 +} + 10C{O}_{2} + 12{H}_{2}O

Number of mole of

KMn{O}_{4}

required per mole of

Fe{C}_{2}{O}_{4} = \dfrac{3}{5}
