Chapter 4, Problem 4.19QP

(a)

Interpretation Introduction

Interpretation:

The given compound has to be classified as soluble or insoluble.

Concept introduction:

Soluble are those which dissolve in a solvent.

Insoluble are those which do not dissolve in a solvent.

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 sulfide 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.
