Chapter 17, Problem 55E

Interpretation Introduction

Interpretation: When pure methanol is mixed with water, the solution gets warmer to touch is ideal or not needs to be determined.

Concept introduction: In an ideal solution, the molecular interaction is identical in all the molecules of the solution. Ideal solution obeys Raoult’s law. In an Ideal solution, heat of the solution is zero, that is, $\Delta H_{\text{solution}}=0$ .
