Question

Select correct statement(s): (I) When excess FeCl3 solution is added to K4[Fe(CN)6] solution, in addition to FeIII[FeII(CN)6]-, FeII[FeIII(CN)6]- is also formed due to side redox reaction. (II) When FeCl2 is added to K3[Fe(CN)6] solution, in addition to FeII[FeIII(CN)6]-, FeIII[FeII(CN)6]- is also formed due to side redox reaction. (III) FeIII[FeII(CN)6]- is paramagnetic while FeII[FeIII(CN)6]- is diamagnetic. (IV) FeIII[FeII(CN)6]- is diamagnetic while FeII[FeIII(CN)6]- is paramagnetic.
