OAE Chemistry study guide
OAE Chemistry · Work through your exam, one topic at a time.
The OAE Chemistry exam is one of the Ohio Assessments for Educators subject-matter tests used by the Ohio Department of Education and Workforce for educator licensure. It is typically taken by candidates seeking an initial teaching license in chemistry, or by currently licensed teachers adding a chemistry endorsement. The test is computer delivered and composed entirely of multiple-choice questions. Its content is organized into six domains: Nature of Science; Matter and Atomic Structure; Chemical Bonding and Molecular Structure; Chemical Reactions and Stoichiometry; Thermodynamics and Kinetics; and Solutions, Acids, and Bases. The OAE Chemistry study guide has 6 sections and about 1,828 words.
01Nature of Science
The Nature of Science domain tests how chemistry claims are built and checked: experimental design, measurement quality, data interpretation, and the limits of models. Questions often ask you to identify variables, apply significant-figure rules, or judge whether a conclusion follows from data.
329 words, about 2 min02Matter and Atomic Structure
This domain tests classification of matter, atomic models, subatomic particles, isotopes, electron configurations, and periodic trends. Expect calculations of average atomic mass and questions that connect position on the periodic table to atomic radius, ionization energy, and electronegativity.
310 words, about 2 min03Chemical Bonding and Molecular Structure
This domain tests how atoms bond and how bonding determines shape, polarity, and properties. Expect Lewis structures, VSEPR geometry, hybridization, intermolecular forces, and comparisons of ionic and covalent substances.
302 words, about 2 min04Chemical Reactions and Stoichiometry
This domain tests balanced equations, reaction classes, mole conversions, limiting reactants, yields, and solution stoichiometry. Most items reward a clear mole map and careful unit tracking.
275 words, about 1 min05Thermodynamics and Kinetics
This domain tests energy flow, calorimetry, enthalpy, entropy, free energy, reaction rates, and catalysis. Thermodynamics answers whether a change is favored; kinetics answers how fast it occurs.
318 words, about 2 min06Solutions, Acids, and Bases
This domain tests concentration, dilution, solubility, electrolytes, colligative properties, pH, neutralization, buffers, and titration. Expect both conceptual comparisons and quantitative pH or dilution calculations.
