Question

what is equivalent mass of feC2o4 when it reacts with acidified kmno4 is (mass of fec2o4= M)​

Answer 1

Answer:

(C2O4)2- will be oxidised to CO2 and Fe2+ will be reduced to Fe(Oxidation state 0) first and then will be oxidised to Fe2O3 in which Fe has oxidation state of +3

So in net reation Fe is oxidised to +3 from +2

4FeC2O4+3KMnO4=2Fe2O3+3K2MnO2+6CO2

so Fe is oxidised to +3 from +2

so eqv wt is the wt of Fe2C2O4
