Chapter 12, Problem 12.15QP

Interpretation Introduction

Interpretation:

Two applications of depression in freezing point have to be mentioned.

Concept Introduction:

Depression in freezing point is the phenomenon of lowering of freezing point of a substance, which is considered as solvent, by adding a non-volatile solute.  It is expresses as –

$\Delta T_f=K_b\times m$

Where,

$\begin{array}{l}\Delta T_f\text{ = depression in freezing point}\\ {\text{K}}_f\text{ = cryoscopic constant}\\ \text{m = molality of the solute}\end{array}$
