Which of the following aqueous solution do you expect to have the lowest freezing point?
0.1 m NH4Cl
0.1 m BaCl2
0.1 m Al2(SO4)3
0.1 m AlCl3
more the number of particles in solution,more the depression in freezing point, lower the freezing point.
Of the following 0.1M aqueous solutions, the one with lowest freezing point is:
