Chapter 4.2, Problem 1PPA

Interpretation Introduction

Interpretation:

The given compounds are to be classified as soluble or insoluble in water.

Concept Introduction:

The solubility of compounds can be predicted on the basis of the solubility rules.

The compounds containing an alkali metal cation or the ammonium ion are water-soluble.

The compounds containing nitrate ion, chlorate ion, perchlorate ion, or acetate ion are water-soluble.

The compounds containing chloride ion, bromide ion, or iodide ion are water-soluble, with the exception of the compounds containing ${\text{Ag}}^{\text{+}}$, ${\text{Hg}}_2^{2+}$, or ${\text{Pb}}^{\text{2+}}$ ions.

The compounds containing sulfate ion are water-soluble, with the exception of the compounds containing ${\text{Ag}}^{\text{+}}$, ${\text{Hg}}_2^{2+}$, ${\text{Pb}}^{\text{2+}}$, ${\text{Ca}}^{\text{2+}}$, ${\text{Sr}}^{\text{2+}}$, or ${\text{Ba}}^{2+}$ ions.

The compounds containing carbonate ions, phosphate ions, sulfide ion and most metal hydroxides are insoluble in water, except for the compounds containing alkali metal cations or ammonium ion.
