Textbook Problem

There are many ionic compounds that dissolve in water to a very small extent. One example is lead(II) chloride. When it dissolves an equilibrium is established between the solid salt and its component ions. Suppose you stir some solid PbCl2 into water. Explain how you would prove that the compound dissolves but to a small extent? Is the dissolving process product-favored or reactant-favored?

pbcl 2 (s) pb 2+ (aq)+2cl (aq)

Interpretation Introduction

Interpretation:

The dissolving process product favored or reactant favored should be explained..

Concept introduction:

Chemical equilibrium is the state of the chemical reaction in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system.

Explanation

In equilibrium amount of reactant and product have no change, which results in absence of observable change (macroscopic level).  While stirring the lead chloride the compound dissolves to a small extent due to approach of water molecule around the lead chloride surface...
