Chapter 14, Problem 129SAE

Interpretation Introduction

Interpretation:

The diagram that represents the ${\text{MgCl}}_{\text{2}}$ in solution needs to be determined.

Concept introduction:

Water is a polar solvent because oxygen has negative charge and hydrogen gas positive charge. When ${\text{MgCl}}_{\text{2}}$ is dissolved in water, it consists of 1 ${\text{Mg}}^{2+}$ and 2 ${\text{Cl}}^{-}$ ions.

Thus, in water, ${\text{MgCl}}_{\text{2}}$ gets completely dissociates as follows:

${\text{MgCl}}_{\text{2}}\left(s\right)\to {\text{Mg}}^{2+}\left(aq\right)+2{\text{Cl}}^{-}\left(aq\right)$
