Chapter 8, Problem 8.98P

Interpretation Introduction

(a)

Interpretation:

By comparison of the solutions of $1\text{ M NaCl}$ and $1{\text{ M CaCl}}_2$ , the solution that represents the higher boiling point is to be identified.

Concept introduction:

The colligative properties refer to those properties that are directly proportional to the number of particles. Thus these properties are only determined from the concentration and do not depend on the nature of the solute.

The depression in melting point, elevation in boiling point, and osmotic pressure are some of the colligative properties that depend on the number of particles of solute.

Interpretation Introduction

(d)

Interpretation:

By comparison of the solutions of $1\text{ M NaCl}$ and $1{\text{ M CaCl}}_2$ , the solution that represents the higher vapor pressure is to be identified.

Concept introduction:

The colligative properties refer to those properties that are directly proportional to the number of particles. Thus these properties are only determined from the concentration and do not depend on the nature of the solute.

The depression in melting point, elevation in boiling point, and lowering of vapor pressure, osmotic pressure are some of the colligative properties that depend on the number of particles of solute.
