Chapter 15, Problem 64QRT

(a)

Interpretation Introduction

Interpretation:

The effect on equilibrium of reaction, ${\text{PbCl}}_{\text{2}}\left(\text{s}\right)\rightleftarrows {\text{Pb}}^{\text{2+}}\left(\text{aq}\right)+2{\text{Cl}}^{-}\left(\text{aq}\right)$ on adding lead nitrate solution has to be stated.

Concept Introduction:

Solubility product relates the solubility of a salt with the concentration of ions present in the salt.  Solubility product holds a direct relation with the solubility of the salt.  The solubility product is the ability of the solid to dissolve in aqueous solution.  The more the solubility product the more the solid dissolves in solution.  It is denoted as $K_{\text{sp}}$.  It is known as solubility product constant.

(b)

Interpretation Introduction

Interpretation:

The effect on equilibrium of reaction, ${\text{PbCl}}_{\text{2}}\left(\text{s}\right)\rightleftarrows {\text{Pb}}^{\text{2+}}\left(\text{aq}\right)+2{\text{Cl}}^{-}\left(\text{aq}\right)$ on adding silver nitrate solution has to be stated.
