The AP Chemistry exam covers aย ton of content. When I say a ton, I mean aย TON. The course covers everything from quantum mechanics and atomic structure to properties of states of matter to acid-base titrations. By the time you've learned all of this, it's more than likely that your brain is filled with a chemistry-soup, with terms like "equilibrium", "orbital", and "redox reaction" floating around in an unorganized fashion. To help you organize information, we've put together this list of study guides for every AP Chemistry unit!

Find the 2020 exam schedule, learn tips & tricks, and get your frequently asked questions answered on Fiveable's Guide to the 2020 AP Exam Updates.

โš›๏ธ Unit 1: Atomic Structure and Properties

Unit 1 is your first taste to chemistry and jumps right in with the foundation of every chemical reaction, molecule, and process: the atom. Atoms make up every single bit of matter in the universe and understanding their structure and properties will help you uncover how it all works. From orbitals to electrons, you'll learn the ins and outs to the quantum world and have a better understanding of why atoms do what they do!

Unit 1.1: Moles and Molar Mass

Unit 1.2: Mass Spectroscopy of Elements

Unit 1.3: Elemental Composition of Pure Substances

Unit 1.4: Composition of Mixtures

Unit 1.5: Atomic Structure and Electron Configurations

Unit 1.6: Photoelectron Spectroscopy

Unit 1.7: Periodic Trends

Unit 1.8: Valence Electrons and Ionic Compounds

๐Ÿงช Unit 2: Molecular and Ionic Structure and Properties

Unit 2 takes you from learning about atoms into how molecules and compounds are structured. You'll learn about why chemical bonds occur, both energetically and through electromagnetic force in ionic compounds. Along with this, by the end of this unit, you'll be able to draw molecular structures and predict molecular geometries. This unit is typically one of the more fun and interesting ones, so enjoy it!

2.1: Types of Chemical Bonds

2.2: Intramolecular Force and Potential Energy

2.3: Structure of Ionic Solids

2.4: Structure of Metals and Alloys

2.5: Lewis Diagrams

2.6: Resonance and Formal Charge

2.7: VSEPR and Bond Hybridization

โš—๏ธ Unit 3: Intermolecular Forces and Properties

In Unit 3, the focus is on the interactionsย between particles, specifically molecules. When molecules aren't perfectly symmetric and organized, they interact through intermolecular forces. Gasses and states of matter are also a topic of discussion, and being able to make calculations using the Ideal Gas Law is especially important.

Unit 3.1: Intermolecular Forces

Unit 3.2: Properties of Solids

Unit 3.3: Solids, Liquids, and Gasses

Unit 3.4: The Ideal Gas Law

Unit 3.5: Kinetic Molecular Theory

Unit 3.6: Deviations from the Ideal Gas Law

Unit 3.7: Solutions and Mixtures

Unit 3.8: Representations of Solutions

Unit 3.9: Separation of Solutions

Unit 3.10: Solubility

Unit 3.11: Spectroscopy and the Electromagnetic Spectrum

Unit 3.12: The Photoelectric Effect

Unit 3.13: The Beer-Lambert Law

๐Ÿ’ฅ Unit 4: Chemicalย Reactions

Chemical reactions are what chemistry is all about. Now that you've learned about how substances work. you can start to uncover how they interact with each other. AP Chem has three specific types of reactions: precipitation, redox, and acid-base. These three types of reactions along with other details of how reactions work and proceed will help you understand what happens when two chemicals mix.

4.1: Introduction for Reactions

4.2: Net Ionic Equations

4.3: Representations of Reactions

4.4: Physical and Chemical Changes

4.5: Stoichiometry

4.6: Introduction to Titration

4.7: Types of Chemical Reactions

4.8: Redox Reactions

๐Ÿ“ˆ Unit 5: Kinetics

Kinetics is a field of chemistry all about the rate of a reaction. How quickly does a reaction proceed? How can we speed it up? Slow it down? Can we calculate how long a reaction will take, and how do we measure how far forward a reaction goes? These questions are all questions that can be answered using kinetics.

5.1: Reaction Rates

5.2: Introduction to Rate Laws

5.3: Concentration Changes Over Time

5.4: Elementary Reactions

5.5: Collision Model

5.6: Reaction Energy Profile

5.7: Introduction to Reaction Mechanisms

5.8: Reaction Mechanisms and Rate Laws

5.9: Catalysts

๐Ÿ”ฅ Unit 6: Thermodynamics

Energy plays a huge role in AP Chemistry and in chemistry as a whole. When chemical reactions occur, a huge part of what happens has to do with energy entering or exiting a system, usually through heat. You'll learn about calorimetry, enthalpy, and bond energy and understand the role of energy in chemistry.

6.1: Endothermic and Exothermic Processes

6.2: Energy Diagrams

6.3: Heat Transfer and Thermal Equilibrium

6.4: Heat Capacity and Calorimetry

6.5: Energy of Phase Diagrams

6.6: Introduction to Enthalpy of Reaction

6.7: Bond Enthalpies

6.8: Enthalpies of Formation

6.9: Hess's Law

โš–๏ธ Unit 7: Equilibrium

How far does a reaction go forward? In chemistry some (in fact most) reactions are reversible, that is to say, the reaction happens, but then the opposite also occurs. When the rates of the forward and reverse reactions are equivalent, the reaction is said to be at equilibrium. In Unit 7, you'll explore reversible reactions and calculate concentrations at equilibrium.

7.1: Introduction to Equilibrium

7.2: Direction of Reversible Reactions

7.3: Reaction Quotient and Equilibrium Constant

7.4: Calculating the Equilibrium Constant

7.5: Magnitude of the Equilibrium Constant

7.6: Properties of the Equilibrium Constant

7.7: Calculating Equilibrium Concentrations

7.8: Representations of Equilibrium

7.9: Introduction to Le Chatelier's Principle

7.10: Reaction Quotient and Le Chatelier's Principle

Our creators are hard at work writing study guides for Unit 7, and this article will be updated as soon as we have them. We're sorry for the inconvenience!
