Chapter 11 Solubilities of Solids in Liquids
The ability of solids to dissolve in liquids varies enormously; in some cases a solid solute may form a highly concentrated solution in a solvent (e.g., calcium chloride in water) and in other cases the solubility may be barely detectable (e.g., paraffin wax in mercury).
In this chapter we consider some of the thermodynamic principles that govern equilibrium between a solid phase and a liquid phase.
11.1 Thermodynamic Framework
Solubility is a strong function of the intermolecular forces between solute and solvent, and the well-known guide “like dissolves like” is no more than an empirical statement indicating that, in the absence of specific chemical effects, intermolecular forces between chemically ...
