Chapter 17, Problem 17.139SP

Interpretation Introduction

(a)

Interpretation:

The concentration of ${\text{Cl}}^{-}$ in $\text{AgCl}$ is to be calculated.

Concept introduction:

Solubility product is equilibrium constant for reaction that occurs when an ionic compound is dissolved to produce ions. It is represented by $K_{\text{sp}}$. Consider ${\text{A}}_x{\text{B}}_y$ to be an ionic compound. Its dissociation occurs as :

${\text{A}}_x{\text{B}}_y\rightleftharpoons x{\text{A}}^{y+}+y{\text{A}}^{x-}$

The expression for its $K_{\text{sp}}$ is as follows:

$K_{\text{sp}}={\left[{\text{A}}^{y+}\right]}^x{\left[{\text{B}}^{x-}\right]}^y$

Interpretation Introduction

(b)

Interpretation:

The concentration of ${\text{Cl}}^{-}$ in ${\text{Hg}}_2{\text{Cl}}_2$ is to be calculated.

Interpretation Introduction

(c)

Interpretation:

The concentration of ${\text{Cl}}^{-}$ in ${\text{PbCl}}_2$ is to be calculated.

Concept introduction:

Interpretation Introduction

Interpretation:

The fraction of ${\text{Pb}}^{2+}$ remain in the solution when ${\text{Ag}}^{+}$ precipitate should be determined
