Chem – LESSON 14: Solutions

What is the lesson about?

Solutions are a mixture of two or more things. In this lesson, you will learn about how chemistry defines mixtures, how it measures those mixtures, and how those mixtures behave as something different from each of their individual components. We live in a world of solutions and so this lesson helps you define how to analyze the solutions around you.


Why is it critical to understand?

Most of the lesson hinges on two sections. First, understand the definition of a solution. Second, focus on the ability to calculate and understand molarity.  Molarity becomes useful for later lessons and that is especially true for AP and college students.


What should you know before attempting this lesson?

If you have trouble in this lesson go back to sections on EquationsSolving for an UnknownUnit Conversions, Calculating the Molar Mass of Compounds, Definition and Layout of a Chemical Equation, States of Matter in a Chemical Equation, Balancing Chemical Equations Part 1, Tips and Tricks for Balancing Equations Part 2, Types of Chemical Equations, Prediction types of Chemical Equations Part 1, , Grams to Moles Conversions and Combining Stoichiometry and Molar Mass.
