Chapter 21, Problem 21.61QP

Interpretation Introduction

Interpretation: The tooth enamel is given to contain the hydroxyapatite mineral. The reaction of hydroxyapatite with fluoride ion results in the formation of fluorapatite as a product. The equilibrium constant $K$ for the reaction is given to be $8.48$. The equilibrium constant expression for the given reaction is to be stated. The direction in which equilibrium lies is to be stated.

Concept introduction: The equilibrium constant expression for the given reaction is written as the ratio of concentration of products to concentrations of reactants.

To determine: The equilibrium constant $K$ for the reaction is given to be $8.48$. The equilibrium constant expression for the given reaction is to be stated and the direction in which equilibrium lies.
