Which of the following 0.10 M aqueous solution will have the lowest freezing point.
Al2(SO4)3
C6H12O6
BaSO4
KI
Depression in freezing point α ii=1+(n−1)α; i α n(if α is same)Al2(SO4)3→2Al+3+3SO−24n=5BaSO4→Ba2++SO2−4 [ΔTf∝1i×m]n=2KI→K++I−n=2
Of the following 0.10 m aqueous solution, which one will exhibit the largest freezing point depression?
