Chapter 12, Problem 76E

Interpretation Introduction

Interpretation: For the given pair of substances ${\text{CH}}_3\text{OH}$ and ${\text{H}}_2\text{O}$, the miscibility should be determined.

Concept introduction: The miscibility of compounds follows the rule of “like dissolves like.” According to this rule, polar liquids dissolve in polar liquids and nonpolar liquids in nonpolar liquids. In other words, nonpolar liquids are miscible with other nonpolar liquids but are not miscible with polar liquids.
