This sample unit is from the 2013 edition of AP Chem Solutions. The content and organization are different in the 2025 edition of AP Chem Solutions, as it follow the Unit Guides in the current Course and Exam Description (CED) for AP Chemistry, but the format is the same. Every unit in the resource package is organized into lesson specific folders. All lessons contain slideshow presentations, slide-by-slide discussion outlines for teachers, notes for students, practice problems, and complete solution keys.
