Chapter 4, Problem 4.7VP

Interpretation Introduction

Interpretation: The ions among the ones depicted in the given figure that will remain in the solution are to be identified.

Concept introduction: The solubility of ions in the solution depends on factors like temperature and amount of solute or ion added into the solution. There are some rules for solubility of ions in the solution. Salts containing ${\text{Cl}}^{-}$, ${\text{Br}}^{-}$, ${\text{I}}^{-}$ are generally soluble. Important exceptions to this rule are halide salts of ${\text{Ag}}^{+}$, ${\text{Pb}}^{2+}$ and ${\left({\text{Hg}}_2\right)}^{2+}$. Thus, $\text{AgCl}$, ${\text{PbBr}}_2$ and ${\text{Hg}}_{\text{2}}{\text{Cl}}_{\text{2}}$ are insoluble.

To identify: The ions among the ones depicted in the given figure that will remain in the solution.
