Use these sample multiple-choice questions to prepare and study for AP exam for Chemistry. A strong emphasis is on writing net ionic equations, knowing the solubility rules, solving equilibrium problems.

Students discover the different types of reactions, and the driving forces behind those reactions. They learn how to write net ionic equations, and learn about specific types of reactions like acid-base neutralization and...

Precipitation Reactions occur when cations and anions of aqueous solutions combine to form an insoluble ionic solid, called a precipitate. Whether or not such a reaction occurs can be determined by using the solubility rules for common...
