A solution of ferrous oxalate has been prepared by dissoliving 3.6 g L

1.	A solution of ferrous oxalate has been prepared by dissoliving 3.6 g L^(-1) calculate the volume of 0.01 M KMnO_(4) solution required for complete oxidatin of 100 mL of lferrous oxalte soluton in acidic medium
Answer» Solution :Molarity of `FeC_(2)O_(4)` solution `=("mass in" gL^(-1))/("MOL mass in" G mol^(-1))=(3.6)/(144)=0.025M` The balanced chemical equation for the redox reaction is : `5FeC_(2)O_(4)+3MinO_(4)^(2-)+24H^(+)rarr5Fe^(3+)+3MN^(2+)10CO_(2)+12H_(2)O` Applying molarity equation we have `(0.01xxV)/(3)(MnO_(4)^(-))=(0.025xx100)/(5)(FeC_(2)O_(4)) "in" V=(0.025xx100xx3)/(5xx0.01)=150 mL`
