Chapter 6, Problem 6I.8E

(a)

Interpretation Introduction

Interpretation:

The molar solubility of silver iodide in $\text{0}\text{.20}\text{M}\text{NaI}{\text{(aq)}}_{}$ 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 calcium carbonate in $\text{2}\text{.3}\times {\text{10}}^{-4}\text{M}{\text{Na}}_2{\text{CO}}_3{\text{(aq)}}_{}$ has to be calculated.

Concept introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

The molar solubility of lead(II) fluoride in $\text{0}\text{.21}\text{M}\text{NaF}{\text{(aq)}}_{}$ has to be calculated.

Concept introduction:

Refer to part (a).

(d)

Interpretation Introduction

Interpretation:

The molar solubility of nickel(II) hydroxide in $0.450\text{M}{\text{NiSO}}_4{\text{(aq)}}_{}$ has to be calculated.

Concept introduction:

Refer to part (a).
