Chapter 16, Problem 123E

Interpretation Introduction

Interpretation:

The molality of solution of an unknown solute in acetic acid that freezes at $\text{14}\text{.1}°\text{C}$ is to be calculated.

Concept introduction:

Colligative properties are defined as the physical properties of some dilute solutions which depend on the molal concentration of the solutes.

The colligative property that is linked to the freezing point of the solution is the depression in freezing point. The change in freezing point is known as the freezing point depression which is denoted by ${\text{ΔT}}_{\text{f}}$.
