1hey since the molalities are same the molecular weights of the substances matter.
i think the answer is KCl one.
is the answer (b)??????????????
The aqueous solution with the lowest
freezing point is
(1) 0.01 m glucose
(2) 0.01 m KCl
(3) 0.01 m BaCl2
(4) 0.01 m K4[Fe(CN)6]?
With explanation please.thanks

1No sorry....Its given as d. I dont know how..do u have any idea?
111)glucose : no dissociation
2)KCl : dissociation into 2 particles
3)BaCl2 : dissociation into 3 particles
4)K4[Fe(CN)6] : dissociation into 5 particles
i (vant Hoff factor) of K4[Fe(CN)6] is max.
(Since molality is also same) Hence max. depression in freezing pt.
Hence lowest freezing pt.
1Answer is glucose C6H12O6
Because decrease in freezing point is colligative property so it doesn't depend on nature of solution
