Praxis Chemistry 5246 Study Guide 2026–2027 | 200 Practice Questions

Prepare for the Praxis® Chemistry (5246) test with a complete study guide organized around the five ETS content categories. Each chapter condenses what the test measures into clear explanations, summary tables, process flows, key-concept boxes, and labeled diagrams, so you can review matter and energy, bonding and structure, reactions and periodicity, and solutions and acid-base chemistry without hunting through a textbook.

This 138-page digital guide pairs a focused content review with two 100-question practice tests of exam-level questions, so you can practice reading data tables, interpreting lab scenarios, solving calculations without a calculator, and judging how to teach a concept, the way the test asks.

What's Inside

• An overview of the current test: 125 selected-response questions in 2 hours 30 minutes, the five content categories and their weights (14/25/20/23/18%), scaled scoring, state-set qualifying scores, the on-screen periodic table and constants table, fees, and retakes
• Nature and Impact of Science and Engineering: the scientific method, measurement and significant figures, laboratory safety, engineering design, and the Science and Engineering Practices and tasks of teaching
• Principles and Models of Matter and Energy: classification of matter, atomic structure and electron configuration, nuclear chemistry and half-life, thermochemistry and Gibbs free energy, and the gas laws
• Chemical Composition, Bonding, and Structure: the mole, nomenclature, ionic and covalent bonding, Lewis structures, VSEPR geometry, intermolecular forces, and types of solids
• Chemical Reactions and Periodicity: periodic trends, reaction types, balancing, stoichiometry and limiting reagents, redox, kinetics and rate laws, and chemical equilibrium
• Solutions and Acid-Base Chemistry: solutions and colligative properties, pH and strong versus weak acids and bases, buffers and titration curves, solubility equilibria, electrochemistry, and aqueous thermodynamics
• 15 labeled science diagrams, a formula and relationship quick reference, and a final review checklist
• Three-month, one-month, and one-week study plans, FAQs, test-taking strategies for a calculator-free test, and recommended resources
• 2 practice tests (200 questions, 4 answer choices each) weighted like the real test's five categories, with data tables and lab scenarios, plus a separate answer key explaining every answer
