Chapter 6, Problem 6I.7E

(a)

Interpretation Introduction

Interpretation:

The molar solubility of silver chloride in $\text{0}\text{.20}\text{M}\text{NaCl}{\text{(aq)}}_{}$ has to be calculated.

Concept Introduction:

Solubility product:

The equilibrium constant is defined as solubility product and it denoted by the symbol of ${\text{K}}_{\text{sp}}$.  It is expressed by the chemical reaction equilibrium between an ionic solid compound and its ions solubility nature in the solution.

Common-ion defect:

The sparingly soluble salt solubility is decreased by the addtion of another soluble salt, because which posses an ion common with both salts.  This is called common-ion effect.

(b)

Interpretation Introduction

Interpretation:

The molar solubility of mercury(I) chloride in $\text{0}\text{.150}\text{M}\text{NaCl}{\text{(aq)}}_{}$ has to be calculated.

Concept introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

The molar solubility of lead(II) chloride in $\text{0}\text{.025}\text{M}{\text{CaCl}}_{\text{2}}{\text{(aq)}}_{}$ has to be calculated.

Concept introduction:

Refer to part (a).

(d)

Interpretation Introduction

Interpretation:

The molar solubility of iron(II) hydroxide in $\text{2}\text{.5}\times {\text{10}}^{-3}\text{M}{\text{FeCl}}_{\text{2}}{\text{(aq)}}_{}$ has to be calculated.

Concept introduction:

Refer to part (a).
