Question
Explain the depression in the freezing point of a solution.
✓
Answer
The depression in the freezing point of a solution is defined as the difference between the freezing points of a pure solvent and that of the solution. If $T_0$ and $T$ are the respective freezing points of a pure solvent and a solution, then the depression in the freezing point $\Delta T_f$ is given by, $\Delta T_f=T_0-T\left(T<T_0\right)$
The depression in the freezing point $\left(\Delta T_f\right)$ is a colligative property.
