Understand the basic types and characteristics of solution formulations in pharmaceutical practice

 * Gas in Gas
 * liquid in liquid
 * solid in solid
 * gas in liquid
 * solid in gas
 * solid in liquid - most common

Define the various types of solutes and solvents, and their interactions with each other

 * Hydrophilic, lipophobic, "water loving" solvents dissolve ions, polar compounds, and solutes with hydrogen bonds. The solute - solvent interactions are generally strong.
 * Hydrophobic, lipophylic "water hating" solvents dissolve hydrocarbons and other similar moieties. The solute - solvent interactions are generally weak.
 * Hydrophilic/Hydrophobic solvents (like alcohols, acids, and amides) have both properties. Overall solubility depends on which characteristics dominate in the molecule.
