Ch 10: Properties of Colloids

About This Chapter

In this overview of properties of colloids, learn about topics like emulsion and chromatography. You can use these video lessons to prepare for a test or supplement class materials.

Properties of Colloids - Chapter Summary

This chapter provides lessons on properties of colloids. There are informative discussions that include adsorption of gases and purification of lyophilic colloids. After completing the chapter, you should be able to do the following:

  • Define and discuss types, protection, and application of colloids
  • Compare solutions, suspensions, and colloids
  • Discuss characteristics of crystalloids
  • Explain emulsion and provide examples
  • Examine adsorption of gases
  • Explore Thomas Graham's system of substance classification
  • Understand preparation and purification of lyophilic colloids
  • Define chromatography and understand types and uses

We use short and interesting video lessons, which help you to quickly grasp the information presented. Our expert instructors are engaging and provide great examples. The video timelines allow you to navigate the videos and jump straight to the topics that are of greatest interest. Full video transcripts are also available for you to review. Each lesson is accompanied by a brief multiple-choice quiz to test your knowledge.

Comparing Solutions, Suspensions & Colloids: Properties & Examples

1. Comparing Solutions, Suspensions & Colloids: Properties & Examples

With a few simple observations, you can classify a mixture as a solution, suspension or colloid. Learn how we use properties, such as visibility of particles, how light is affected and the ability of particles to settle out to classify mixtures.

Colloids: Definition, Types & Examples

2. Colloids: Definition, Types & Examples

In this lesson, you will learn the definition of colloids. There will be examples provided to assist you with your understanding of the topic. Also, several types of colloid solutions are provided.

Crystalloids: Definition & Examples

3. Crystalloids: Definition & Examples

This lesson focuses on defining crystalloids and fluid tonicity. Examples of IV solutions used in clinical practice are also discussed. By the end of this lesson, you'll also be able to explain the categories of crystalloids.

Emulsion: Definition & Examples

4. Emulsion: Definition & Examples

Oil and water don't mix! In this lesson learn about emulsions and how they work. Through examples, learn about their abundance in foods and what kinds of foods use an emulsion.

Adsorption of Gases: Definition & Examples

5. Adsorption of Gases: Definition & Examples

Adsorption of gases are all around us and can affect our day-to-day life. In this lesson, we learn specifically about adsorption of gases and how it is measured.

Thomas Graham's System of Substance Classification

6. Thomas Graham's System of Substance Classification

Thomas Graham was the first scientist to classify substances as colloids or crystalloids. In this lesson, we will learn how he described these categories and how those categories have been further defined.

Preparation & Purification of Lyophilic Colloids

7. Preparation & Purification of Lyophilic Colloids

Lyophilic colloids are colloids where the particles have a strong affinity with the liquid. In this lesson we will learn about lyophilic colloids and how they are prepared and purified.

What is Chromatography? - Definition, Types & Uses

8. What is Chromatography? - Definition, Types & Uses

Chromatography is a versatile method of separating many different kinds of chemical mixtures. In this lesson, learn the different types and uses of the technique.
