Question

5 mol of mixture of Mohr’s salt and Fe2(SO4)3 requires 500mL of MK2Cr2O7 for complete oxidation in acidic medium. The mole % of the Mohr’s salt in the mixture is

Solution

Correct option is

60

 

                                        

Eq. of Fe2+ (= moles of Mohr’s salt) = Eq. of K2Cr2 O7

(n=factor of K2Cr2 O7 = 6)
