0.01 M solution of KCI and $C a C l_{2}$ are separately prepared in water. The freezing point of KCI is found to be $- 2^{o} C$ . What is the freezing point of $C a C l_{2}$ aq. solution if it is completely ionized?

Options:

Answer:

Solution:

$i f o r K C l = 2, i f o r f o r C a C l_{2} = 3$

$∆ T_{f} \propto i$

$\frac{∆ T_{f} (K C l)}{∆ T_{f} (C a C l_{2})} = \frac{2}{3}$

$∆ T_{f} (C a C l_{2}) = \frac{3}{2} \times 2 = 3^{o} C$

Freezing point of $C a C l_{2} = - 3^{o} C$
