Chapter 13.6, Problem 13.8BFP

Interpretation Introduction

Interpretation:

The lowest molality of ethylene glycol solution that protects the car’s coolant from freezing at $\text{0}{\text{.00}}^{\text{o}}\text{F}$ has to be calculated.

Concept Introduction:

Freezing point depression: It occurs due to the vapor pressure of the solution is always lower than that of the solvent. Thus, the solution freezes at a lower temperature.

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

Where,

${\text{K}}_{\text{f}}$ is the molal freezing point depression constant.
