OSAT Chemistry (104) Study Guide 2027–2028 | Oklahoma Chemistry Teacher Certification Exam Prep, 200 Questions (PDF)

Prepare for the Oklahoma Subject Area Test (OSAT) in Chemistry, test code 104, used for Oklahoma chemistry teacher certification. Every section follows the official 12-competency framework, both practice tests are weighted like the real selected-response subareas, and the constructed-response assignment is taught step by step.

What's Inside

• Exam overview: 80 selected-response questions plus one constructed-response assignment, 4 hours of testing time, the on-screen calculator and periodic table, the 240 passing score on the 100-300 scale, score reports, retakes and fees

• Structure and Properties of Matter: atomic structure, isotopes and electron configurations; nuclear chemistry, light and spectra; the periodic table and periodic trends; bonding, formulas and nomenclature; Lewis structures, VSEPR shape and polarity; mixtures, solutions and colligative properties; intermolecular forces, states of matter and gases

• Chemical Reactions: reaction types, net ionic equations, acids and bases and redox; the mole, stoichiometry, titration and gravimetric analysis; reaction kinetics and mechanisms; chemical equilibrium, Le Chatelier's principle and buffers

• Energy Changes: calorimetry, heating curves, bond energies, the Born-Haber cycle and nuclear energy; thermodynamics, Hess's law, entropy, Gibbs free energy and electrochemistry

• The constructed-response assignment: the five required parts, how it is scored, lab safety, storage and disposal, analyzing student work, a planning template and two illustrative prompts with model response excerpts

• Diagrams and 160+ quick-reference tables, plus worked examples, Lab Scenarios, Data Checks, Calculator Tips and a Quick Check in every section

• Study schedules, FAQs and test-taking strategies
