Chapter 9, Problem 9.29UKC

Interpretation Introduction

Interpretation:

The curve that represent the change in boiling point of an aqueous solution when $1mole$ of $HF$ is added to $1kg$ of water and $1mol$ of $HBr$ has to be identified.

Concept introduction:

• When the vapor pressure of a pure solvent is lowered the boiling point of a solvent is raised by the presence of a nonvolatile solute and is given by

$\Delta T_{boiling}=\left({0.51}^{o}C\frac{kgwater}{molparticles}\right)\left(\frac{molparticles}{kgwater}\right)$

• Boiling point is the temperature at which vapor pressure is equal to the $1atm$ pressure.
• Vapor Pressure is the pressure exerted by vapor in equilibrium with the liquid state.
