The 1972 AP Chemistry free-response section is a classic set of problems that covers foundational topics still relevant to today's curriculum, including stoichiometry, acid-base chemistry, and coordination compounds. The primary areas tested in this exam include:

In 1972, the AP Chemistry free-response section heavily emphasized physical chemistry, quantitative problem-solving, and laboratory logic. While the modern AP Chemistry exam includes more conceptual explanations and data analysis, the underlying mathematical rigor remains identical. The primary areas tested in this exam include: Solubility product constants ( Kspcap K sub s p end-sub ) and gas-phase equilibrium ( Kpcap K sub p
