Chemistry - Liquid Solution Question with Solution | TestHub

Explain Question :

Freezing point of solution is maximum

Concept :

Depression in freezing point (ΔT_f )

Solution :

Urea NaCl AlCl₃ glucose

[C] 0.1M 0.1M 0.05 M 0.15 M

i = assuming 100% ionisation

i 1 2 4 1

[C]_net = i × C

Urea NaCl AlCl₃ glucose

[C]_net 0.1 0.2 0.2 0.15

ΔT_f ∝ [C]_net

([C]_net = minimum, ΔT_f = minimum, freezing point = Maximum)

Final Answer (A)
