Ch 9: AP Chemistry: Solutions

About This Chapter

Watch video lessons on solutions and learn about dissolution, molarity, dilution, and more. These lessons are just a portion of our AP Chemistry course.

AP Chemistry: Solutions - Chapter Summary and Learning Objectives

A solution - one substance dissolved in another - is a cornerstone of chemistry theory and experimentation. In this chapter, you'll learn the different types of solutions and what factors affect them. The chapter is broken down into smaller lessons that focus on different aspects of chemical solutions. You'll discover how much of a substance can be dissolved in a solution and how to calculate concentrations and more. This chapter is designed to teach you:

  • How chemical bonds affect the nature of solutions
  • How to calculate concentration, dilution, molecules, and mass
  • The ways various substances form solutions
  • How solutions are used in chemistry experiments
