An equimolar mixture of ferrous oxalate & stannous chloride is treated

1.	An equimolar mixture of ferrous oxalate & stannous chloride is treated with decinormal acidic KMnO_4giving ferric, stannic & chlorate ions along with CO_2gas. If the titre value is 225 ml. Numbers of millimoles of chlorate ions produced are
Answer» 1.5 m moles 7.5 m moles 3 m moles 2.64 m moles Solution : LET millimoles of `FeC_(2)O_(4)=SnCl_(2)=x` n-factor of `FeC_(2)O_(4)=3` n-factor of `SnCI_(2)=14` `:. 3x + 14 x = 0.1 xx 225` `implies 17x = 22.5 implies x = (22.5)/17` m.moles of `ClO_(3)^(-) ` FORMED `=(22.5)/17xx2=2.64`
