Chapter 17.5, Problem 11PPB

(a)

Interpretation Introduction

Interpretation:

From the given compounds, the compounds that are more soluble in acidic solution compared to water have to be identified.

Concept introduction:

• If dissociation of salt forms strong conjugate base, then it is more soluble in acidic compared to water.
• An anion reacts with acid only if it is conjugate base of a weak acid.

To identify: The ${\text{Mg(OH)}}_{\text{2}}$ is more soluble in acidic solution compared to water.

(b)

Interpretation Introduction

Interpretation:

From the given compounds, the compounds that are more soluble in acidic solution compared to water have to be identified.

Concept introduction:

• If dissociation of salt forms strong conjugate base, then it is more soluble in acidic compared to water.
• An anion reacts with acid only if it is conjugate base of a weak acid.

To identify: The ${\text{Ag}}_{\text{2}}{\text{CO}}_{\text{3}}$ is more soluble in acidic solution compared to water.

(c)

Interpretation Introduction
