Chapter 16, Problem 16.68P

Interpretation Introduction

Interpretation:

The solution that will have the highest boiling point has to be identified and the reason for it has to be given.

Concept Introduction:

Boiling point elevation:

The boiling point of a solution is higher than the boiling point of the pure solvent.  The amount by which the boiling point of solution exceeds the boiling point of the pure liquid that is called the boiling point elevation.  The mathematical relationship is given below.

  $\Delta T_b=T_b-T_b{}^{\circ }=K_b{m}_c=K_b\left(i\times m\right)$

Where, $\Delta T_b$ is boiling point elevation, $T_b$ is the boiling point of solution, $T_b{}^{\circ }$ is the boiling point of pure solvent, $K_b$ is the boiling point elevation constant and $m_c$ is the colligative molality.
