AP Chemistry Unit 3 Full Review: IMFs, Gases, Solutions & Spectroscopy (with Simulations)

The complete AP Chemistry Unit 3 review: Properties of Substances and Mixtures, the biggest unit on the AP exam (18–22%). Every topic explained step by step with interactive simulations, worked examples and quick checks. ▶ Try every simulation in this video, free: https://apchemistrytutoring.com/units/3/ ▶ Practice all 128 Unit 3 questions (with worked explanations): https://apchemistrytutoring.com/units... ▶ Free AP Chemistry cheat sheets for all 9 units (PDF): https://apchemistrytutoring.com/#sheet ▶ One-to-one AP Chemistry tutoring, $20 for 30 minutes: https://apchemistrytutoring.com/book/ CHAPTERS 0:00 Introduction 0:29 Intermolecular forces: London dispersion, dipole-dipole, hydrogen bonding, ion-dipole 8:14 Types of solids: ionic, molecular, metallic, covalent network 13:29 Solids, liquids and gases: phase changes and vapor pressure 16:42 Gases: ideal gas law, gas laws, Dalton's law, KMT, Maxwell–Boltzmann 26:28 Solutions: molarity, dilution and chromatography 31:36 Light and spectroscopy: the EM spectrum and Beer's law 37:08 Review of the whole unit + homework WHAT YOU'LL LEARN • How to identify every intermolecular force, and use IMFs to rank boiling points • Why boiling breaks IMFs, not covalent bonds (a classic AP mistake) • The four types of solids and how structure explains their properties • Vapor pressure, boiling point and phase changes • PV = nRT, the gas laws, partial pressures, and why temperature must be in kelvin • Kinetic molecular theory, real vs ideal gases, and Maxwell–Boltzmann distributions • Molarity and dilution (M₁V₁ = M₂V₂), and how chromatography separates by polarity • E = hν, which radiation causes which transition, and Beer's law (A = εbc) HOMEWORK Work through all 128 Unit 3 practice questions on the website, then try the free-response questions on the Unit 3 topic pages.
