Chapter 12, Problem 12.81QP

(a)

Interpretation Introduction

Interpretation:

Among the solutions, the solution with higher boiling point should be identified.

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 at temperature ${\text{100}}^{\text{o}}\text{C}$.

${\text{ΔT}}_{\text{b}}{\text{= T}}_{\text{b}}{\text{- T}}_{\text{b}}^{\text{°}}$

Where,

${\text{ΔT}}_{\text{b}}-$ Change in boiling point

${\text{T}}_{\text{b}}-$ Boiling point of the solution

${\text{T}}_{\text{b}}^{\text{°}}-$ Boiling point of pure solvent

Solubility is said to be one of the chemical property which implies that at equilibrium the maximum amount of solute dissolved in the solvent to gives solution called ‘saturated solution’.

(b)

Interpretation Introduction

Interpretation:

The solutions have same vapor pressure at last should be explained.
