Chapter 13.7, Problem 13.17CE

Interpretation Introduction

Interpretation:

The factor ${\text{i}}_{\text{solute}}$ for the dissociation of the salt ${\text{CaCl}}_2$ has to be calculated.

Concept Introduction:

Freezing point is the temperature at which liquid turns into solid.

TheFreezing point depression${\text{(ΔT}}_{\text{f}}\text{)}$ is indicated as

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

Where,

${\text{ΔT}}_{\text{f}}-$ Change in freezing point

${\text{K}}_{\text{f}}-$ Molal freezing point constant

$m-$ Molality of the solution
