Expert Solution
Step 1: Introduce Depression in Freezing Point

Depression in Freezing point is the lowering of Freezing point of the solution on addition of solute.

Mathematically, it can expressed as:

bold increment bold T subscript bold f bold equals bold K subscript bold f bold cross times bold m where comma increment straight T subscript straight f equals Difference space in space freezing space point space of space pure space solvent space and space solution straight K subscript straight f space equals Cryscopic space constant straight m space equals molality
