As 0.10MC2H5OH is non-dissociative in nature and all salts [0.10MBa3(PO4)2,0.10MNa2SO4, 0.10MKCl,0.10MLi3PO4] are electrolyte and dissociative in nature. ΔTf=iKfm Where i is van’t Hoff factor. i > 1 for all other electrolytes where dissociation takes place. So, for all these electrolytes effective molarity is more than 0.10. So, all the elecrolytes given will have low freezing point.
