Chapter 12, Problem 12.103QE

(a)

Interpretation Introduction

Interpretation:

The molality of the solute in each of the two solutions has to be calculated.

Concept Introduction:

Freezing point depression:  The freezing point depression is proportional to the concentration of the solute particles and is given by the equation,

  ΔTf=imkf

Here,

  ΔTf= Freezing point of the solution

  m= Molal concentration

  kf= Freezing point depression constant (depends on the solvent used).

  i= van’t Hoff factor

(b)

Interpretation Introduction

Interpretation:

The van’t Hoff factors for benzene and water solutions have to be given.

Concept Introduction:

van’t Hoff factor, i:  The van’t Hoff factor is given by the equation,

  i=measuredcolligativepropertyexpectedvalueforanonelectrolyte

For solutions that are nonelectrolytes, like urea and sucrose, the van’t Hoff factor is one.  For solutions of salts and other electrolytes, the value of i is greater than one.  For dilute solution such as (0.01m or less), the van’t Hoff factor will be equal to the number of ions formed by each formula unit of the compound that dissolves.

(c)

Interpretation Introduction

Interpretation:

The difference in the van’t Hoff factors of acetic acid in benzene solution and water solution has to be explained
