Chapter 10, Problem 115CWP

Interpretation Introduction

Interpretation: The boiling point of given solution was calculated.

Concept Introduction:

Colligative properties of a substance include the depression in the freezing point, elevation of boiling-point and osmotic pressure. These are dependant only on the number present and not based on the solute particles present in an ideal solution. These properties have a direct relationship to the solute particles, and therefore the colligative properties are useful for identifying the nature of solute particles and also calculating the molar masses of substances.

The change in boiling-point expressed by the given equation

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

Here ${\text{K}}_{\text{b}}$ is molal boiling-point elevation constant.
