Chapter 13, Problem 13.40QP

Interpretation Introduction

Interpretation:

Vapor pressure lowering related to rise in the boiling point of a solution has to be discussed.

Concept introduction

• Boiling point is the temperature at which liquid turns into a gas. Example: boiling point of water is $\text{100°C}$. That is water changes from liquid phase to gas phase.
• Boiling point elevation$(\Delta T_b)$ is distinction between boiling point of the pure solvent ${\text{(T}}_{\text{b}}^{\text{°}}\text{)}$ and the boiling point of the solution ${\text{(T}}_{\text{b}}\text{)}$.
• Vapor pressure is the pressure excreted by the molecules at the surface of the liquid in the closed container.
