Question

Number of moles of `MnO_(4)^(-)` required to oxidise one mole of ferrous oxalate completely in acidic medium will be
A. 7.5 moles
B. 0.2 moles
C. 0.6 moles
D. 0.4 moles

Answer 1

Correct Answer - D
`2MnO_(4)^(-)+16H^(+)+5C_(2)O_(4)^(2-) to 2Mn^(2+)+10CO_(2)`
Number of moles of `MnO_(4)^(-)` required to oxidise `=(2)/(5)=0.4`
