AP Chemistry

Acids, Bases, Titration

Most acid/base problems will test your knowledge of equilibrium, specifically whether or not you can determine concentration and equilibrium constants.

Gas Equilibrium

Gas equilibrium problems will ask you to ascertain total or partial pressures, mole fraction and concentration, and equilibrium constants. You should also know how other factors such as temperature and volume of containers affect gas equilibrium.

Molecular Bonding

Most molecular bonding problems do not involve any calculations, instead they ask you to use your knowledge of bonding to explain specific characteristics of a molecule. These characteristics usually include melting/boiling/freezing points, polarity, and/or solubility. Deep understanding of intermolecular forces and Lewis structures are necessary; many bonding problems require you to draw or examine a Lewis structure.

Bonding questions may also test the properties of individual elements, particularly comparing the ionization energy, electron affinity, atomic radii, et cetera between elements.
