Chapter 4, Problem 26E

(a)

Interpretation Introduction

Interpretation: The concentration of all ions present in $\text{100}\text{mL}$ solution containing $\text{0}\text{.100}$ mole of $\text{Ca}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}$ is to be calculated.

Concept introduction: When any electrolyte is introduced in water, it generates ions in the solution owing to its dissociation. These ions are really helpful in conducting electricity. The concentration of generated anions and cations is dependent completely on the electrolytes’ composition and its amount.

(b)

Interpretation Introduction

Interpretation: The concentration of all ions present in $\text{1}\text{.25}\text{L}$ solution containing $2.5$ mole of ${\text{Na}}_{\text{2}}{\text{SO}}_{\text{4}}$ is to be calculated.

Concept introduction: When any electrolyte is introduced in water, it generates ions in the solution owing to its dissociation. These ions are really helpful in conducting electricity. The concentration of generated anions and cations is dependent completely on the electrolytes’ composition and its amount.

(c)

Interpretation Introduction

Interpretation: The concentration of all ions present in $\text{5}\text{.0}\text{g}$ of ${\text{NH}}_{\text{4}}\text{Cl}$ in $\text{500}\text{.0}\text{mL}$ solution is to be calculated.

Concept introduction: When any electrolyte is introduced in water, it generates ions in the solution owing to its dissociation. These ions are really helpful in conducting electricity. The concentration of generated anions and cations is dependent completely on the electrolytes’ composition and its amount.

(d)

Interpretation Introduction

Interpretation: The concentration of all ions present in $\text{1}\text{.0}\text{g}$ of ${\text{K}}_{\text{3}}{\text{PO}}_{\text{4}}$ in $\text{250}\text{.0}\text{mL}$ solution is to be calculated.
