Interpretation Introduction

Interpretation:

In water solubility of given compounds are should be given.

Concept introduction:

Solubility guideline:

• Compound containing alkali metal cations and ammonium ion are soluble in water.
• Compound contains nitrate, acetate and chlorate ions are soluble in water.
• Except  ${\text{Ag}}^{\text{+}}$ , ${\text{Hg}}^{\text{2+}}$ and ${\text{pb}}^{\text{2+}}$ ions , compounds containing chloride, bromide and iodide ions are soluble in water.
• Except ${\text{Ag}}^{\text{+}}$ , ${\text{Hg}}^{\text{2+}}$, ${\text{pb}}^{\text{2+}}$, ${\text{Ca}}^{\text{2+}}$, ${\text{Sr}}^{\text{2+}}$ and ${\text{Ba}}^{\text{2+}}$ ions, compounds containing sulfate ion are soluble.
• Except ${\text{Li}}^{\text{+}}$ , ${\text{Na}}^{\text{+}}$ , ${\text{K}}^{\text{+}}$ , ${\text{Rb}}^{\text{+}}$ , ${\text{Cs}}^{\text{+}}$ and ${\text{NH}}_{\text{4}}{}^{\text{+}}$ ions, compounds containing carbonate, phosphate, chromate and sulfite ions are insoluble in water.
• Except ${\text{Li}}^{\text{+}}$ , ${\text{Na}}^{\text{+}}$ , ${\text{K}}^{\text{+}}$ , ${\text{Rb}}^{\text{+}}$ , ${\text{Cs}}^{\text{+}}$ and ${\text{Ba}}^{\text{2+}}$ ions, compounds containing hydroxide ions are insoluble in water.

Answer to Problem 2PPB

The water solubility of given compounds are,

${\text{MgBr}}_{\text{2}}$ issoluble in water.

Explanation of Solution

According to the solubility guideline, ${\text{MgBr}}_{\text{2}}$ is contains ${\text{Br}}^{\text{-}}$ ion with ${\text{Mg}}^{\text{2+}}$ so it is soluble in water.
