Ch 30: CEOE Middle Level Science: Mixtures & Solutions

About This Chapter

Review facts about mixtures and solutions in this chapter of the CEOE Middle Level Science exam study guide. Video lessons and self-assessment quizzes teach you all you need to know about middle level science for teacher licensure in Oklahoma.

CEOE Middle Level Science: Mixtures and Solutions - Chapter Summary

Lessons in this chapter explore mixtures and solutions, including properties of water, colligative properties, and calculating dilutions of solutions. Raoult's law, molarity and molality concentration, and rate of dissolution are also covered. Additionally, by the end of this chapter, you should be familiar with:

  • Solubility and solubility curves
  • Solutions, electrolytes and nonelectrolytes
  • Chromatography, distillation and filtration
  • Osmosis, diffusion and saturation
  • Acids and bases

Knowledgeable instructors walk you through each subject through short, engaging video lessons. Self-assessment quizzes can be used to test your knowledge, or print them as worksheets to help you study. The jump feature under the Timeline tab allows you to skip directly to main subjects within the video lessons.

Mixtures and Solutions - Chapter Objectives

The CEOE Middle Level Science exam measures a student's knowledge of subject matter in accordance with Oklahoma educator licensure regulations. The exam measures foundations of scientific inquiry, life science, physical science, and earth and space science. The material covered in this Mixtures and Solutions chapter is tested in the physical science portion of the CEOE exam, which comprises about 32% of the entire test. The exam includes approximately 80 multiple-choice questions and one open-response question.

Solutions, Solutes, and Solvents

1. Solutions, Solutes, and Solvents

Oh no! Your friend Ben just drank chili oil on a dare, and now his mouth is burning. Should he drink the ice water or vegetable oil to cool his mouth? Quick. Watch this lesson if you aren't sure.

Properties of Water

2. Properties of Water

Why does ice float? Why can water rise on its own against gravity in a small tube? Find out how these mysterious properties of water can be explained by hydrogen bonds.

Using Colligative Properties to Determine Molar Mass

3. 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.

Calculating Dilution of Solutions

4. 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

5. 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.

Calculating Molarity and Molality Concentration

6. Calculating Molarity and Molality Concentration

Learn the abbreviations and meaning of molarity and molality. Then apply what you have learned by going over some sample calculations with given concentrations.

The Rate of Dissolution: Factors and Definition

7. 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.

Solubility and Solubility Curves

8. 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.

Solutions, Electrolytes and Nonelectrolytes

9. 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.

Chromatography, Distillation and Filtration: Methods of Separating Mixtures

10. Chromatography, Distillation and Filtration: Methods of Separating Mixtures

What are some ways that mixtures can be separated? Watch this video to explore several examples of ways you can separate a mixture into its individual components.

Osmosis, Diffusion and Saturation

11. Osmosis, Diffusion and Saturation

The cells in our bodies are in constant flux through the processes of osmosis and diffusion. Learn about how saturation levels force change, and why we're lucky they do.

Acids and Bases

12. Acids and Bases

Have you ever wondered how we measure the acidity of liquids? Check out this lesson to see how acids and bases are measured on a pH scale and how they relate to neutral solutions, such as water.
