1 mole of equimolar mixture of ferric oxalate and ferrous oxalate requres x mole of `KMnO_(4)` in acidic medium for complete oxidation. X is:

Options

A. 1.5m moles
B. 7.5m moles
C. 3m moles
D. 2.64 m moles

Answer

D

Explanation

Let millimoles of `FeC_(2)O_(3)O_(4) = SnCl_(2) = x`
n-factor of `FeC_(2)O_(4) = 3`
n-factor of `SnCl_(2) = 14`
`:. 3x +14 x = 0.1 xx 225 rArr 17 x = 22.5 rArr x = (22.5)/(17)`
m moles of `ClO_(3)^(-)` formed `=(22.5)/(17) xx 2 = 2.64`
