Chapter 11, Problem 19QP

Interpretation Introduction

Interpretation:

The relative strengths of the intermolecular forces between NaOH and water, and between the particles in pure substances are to be explained.

Concept Introduction:

The solution turns cool, when ammonium nitrate is dissolved in water. Thus the reaction is endothermic. The energy difference between the energy required to dissociate the solute (or solvent) molecules $\left({\text{E}}_{\text{1}}\right)$ and the energy released while forming the new intermolecular forces between the solute and solvent molecules $\left({\text{E}}_{\text{2}}\right)$ is called Heat of Solution.
