Chapter 9.1, Problem 9.4QAP

Interpretation Introduction

Interpretation:

Formation of an aqueous solution of $\text{LiBr}$, when solid $\text{LiBr}$ is dissolved in water.

Concept introduction:

• $\text{LiBr}$ is an ionic solutes, there are strong ionic bonds between positively charged ${\text{Li}}^{\text{+}}$ ions and negatively charged ${\text{Br}}^{\text{-}}$ ions

• Water is a polar solvent, in which the hydrogen bonds provide strong solvent–solvent attractions.

• When solid $\text{LiBr}$ is dissolved in water, an aqueous solution of $\text{LiBr}$ is formed consisting of ${\text{Li}}^{\text{+}}\text{(aq)}$ and ${\text{Br}}^{\text{-}}\text{(aq)}$ ions.
