These written overviews of the lessons will provide you with an additional review of the material and help you review the key vocabulary of the chapter. After each lesson, test your retention of the information by taking the lesson quizzes. Following these quizzes, use the video tags to improve your understanding of the material you missed.

WEST Chemistry: Properties of Solutions Objectives

Individuals wanting to earn a chemistry endorsement for their Washington teacher's certificate take the WEST-E: Chemistry exam. This computer-based certification exam uses 110 multiple-choice questions, administered in a two-hour and 30-minute testing session, to assess future chemistry teachers' knowledge of the study of chemistry. On test day, you can expect 12% of this exam to be about stoichiometry and solutions, including some questions about the properties of solutions.

The Rate of Dissolution: Factors and Definition

1. The Rate of Dissolution: Factors and Definition

Learn what dissolution is and the factors that affect the rate of dissolution, such as temperature, surface area, polarity and pressure. Learn what miscible and immiscible mean in regards to liquids.

Solutions, Electrolytes and Nonelectrolytes

2. Solutions, Electrolytes and Nonelectrolytes

Learn what a solution is and how it is formed. Learn how to express the concentration of a solution in terms of molarity, molality and mass percent. Discover the differences between an electrolyte and a nonelectrolyte.

Solubility and Solubility Curves

3. Solubility and Solubility Curves

Learn what solubility is as well as the definitions of 'saturated,' 'unsaturated' and 'supersaturated.' Learn how to determine the solubility of a substance in water by using a solubility curve. Discover the effects of pressure and temperature on the solubility of liquids, solids and gases.

Solubility of Common Salts: Predicting Reaction Outcomes

4. Solubility of Common Salts: Predicting Reaction Outcomes

Ever wondered why some salts dissolve in water and others don't? In this lesson you will learn about some simple salt solubility rules. Using these rules, you will be able to predict the products of many chemical reactions.

Calculating Molarity and Molality Concentration

5. Calculating Molarity and Molality Concentration

Learn the abbreviations and meaning of molarity and molality and go over some sample calculations with given concentrations.

Calculating Dilution of Solutions

6. Calculating Dilution of Solutions

Learn what a solution is and how to properly dilute a new solution from a stock solution. Learn the dilution equation that combines molarity, the volume of stock solution and desired solution to determine how much stock solution is needed for the new solution.

Colligative Properties and Raoult's Law

7. Colligative Properties and Raoult's Law

Learn how vapor pressure and osmotic pressure are colligative properties. Learn Raoult's Law and how to use it to determine the vapor pressure of a solution. Learn the equation for determining osmotic pressure and how to use it to determine the molar mass of a substance.

Using Colligative Properties to Determine Molar Mass

8. Using Colligative Properties to Determine Molar Mass

In this lesson, we will explore the effect of colligative properties on a solution. We will learn how to calculate freezing point depression and see how it can be used to calculate the molar mass of an unknown substance.

The Solubility of Gases in a Liquid

9. The Solubility of Gases in a Liquid

In this video lesson, you will learn what solubility is and the factors that affect gas solubility. We will use real-life examples to illustrate the importance of understanding solubility. A quick quiz will then test our new knowledge.
