Chapter 5, Problem 5E.5AE

(i)

Interpretation Introduction

Interpretation:

The molar solubility of ${\text{NH}}_{\text{4}}\text{Cl}$ in water has to be calculated.

Concept introduction:

The molar solubility is defined as the number of moles that can be dissolved in per litre of the solution so as to obtain a saturated solution.  The expression for the solubility is,

    $\text{Solubility}=\frac{n}{\text{Volume}\text{of}\text{the}\text{solution}}$

Where,

• $n$ is the number of moles.

(ii)

Interpretation Introduction

Interpretation:

The molar solubility of ${\left({\text{NH}}_{\text{4}}\right)}_2{\text{SO}}_4$ in water has to be calculated.

Concept introduction:

The molar solubility is defined as the number of moles that can be dissolved in per litre of the solution so as to obtain a saturated solution.  The expression for the solubility is,

    $\text{Solubility}=\frac{n}{\text{Volume}\text{of}\text{the}\text{solution}}$

Where,

• $n$ is the number of moles.
