Chapter 17, Problem 17.109SP

Interpretation Introduction

(a)

Interpretation:

The decreases of solubility of ${\text{Ag}}_{\text{2}}{\text{CO}}_{\text{3}}$ on addition of ${\text{AgNO}}_3$ should be explained.

Concept introduction:

The solubility of compounds depends on pH of solution. Also, the solubility of compound such as oxide and strong base is dependent on pH.

The pH of ionic compound is inversely proportional to solubility. The solubility of salt that has basic anion will increase. If strong acid is added to solution, the concentration of anion decrease which decreases the magnitude of ion form.

In accordance to Le Chatelier’s principle, acidic pH increases the solubility of salt that has anion is conjugate base of weak acid. Also, pH has no effect on the solubility of salt that has anion of conjugate base of strong acid.

Interpretation Introduction

(b)

Interpretation:

The increase of solubility of ${\text{Ag}}_{\text{2}}{\text{CO}}_{\text{3}}$ on addition of ${\text{HNO}}_3$ should be explained.
