Chapter 6, Problem 69P(choose chapter or problem)
Consider the dissolution of an ionic compound such as potassium fluoride in water. Break the process into the following steps: separation of the cations and anions in the vapor phase and the hydration of the ions in the aqueous medium. Discuss the energy changes associated with each step. How does the heat of solution of KF depend on the relative magnitudes of these two quantities? On what law is the relationship based?

ANSWER:Step 1 of 4
The solid dissolves in water and ions are held together by strong electrostatic forces.
The separated ions are stabilized in solution by their interaction with water molecules.
