Chapter 13, Problem 13.143QP

Interpretation Introduction

Interpretation:

Freezing point of the solution has to be calculated.

Concept introduction:

Freezing point: The temperature at which a liquids turns into solid.

Freezing point depression ${\text{(ΔT}}_{\text{f}})$: Freezing point depression is the distinction between freezing point of the pure solvent ${\text{(T}}_{\text{f}}\text{°)}$ and freezing point of the solution ${\text{(T}}_{\text{f}}\text{)}$

${\text{ΔT}}_{\text{f}}{\text{= K}}_{\text{f}}\text{m}$

Where,

$\begin{array}{l}{\text{ΔT}}_{\text{f}}\text{= Change in freezing point}\\ {\text{T}}_{\text{f}}\text{= Freezing point of the solution}\\ {\text{T}}_{\text{f}}\text{°= Freezing point of pure solvent}\end{array}$
