Number of moles of MnO₄⁻ required to oxidize one mole of ferrous oxalate

Number of moles of MnO₄⁻ required to oxidize one mole of ferrous oxalate completely in acidic medium will be

(a) 0.6 moles
(b) 0.4 moles
(c) 7.5 moles
(d) 0.2 moles

0.6 moles

10FeC2O4 + 6KMnO4 + 24H2SO4 —-> 3K2SO4+ 6MnSO4 + 5Fe2(SO4)3 + 24H2O + 20CO2

From the above balanced equation, we observe that

6 moles of KMnO4 is required to oxidize 10 moles of FeC2O4

Then, 1 mole of FeC2O4 would be oxidized by = 6/10=0.6
