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

A mixture of substances appears differently depending on if the substances actually mix, and are evenly distributed. Learn the properties of the three types of mixtures commonly observed through examples of solutions, suspensions, and colloids.

Colloids: Definition, Types & Examples

2. Colloids: Definition, Types & Examples

A colloid is a mixture that contains at least two intermediate sized particles in solid, liquid, or gas form. Learn about the definition, types, and real-world examples of colloids.

Crystalloids: Definition & Examples

3. Crystalloids: Definition & Examples

Crystalloids are a type of intravenous fluid containing electrolytes and dextrose used in clinical therapy. There are three types of crystalloid solutions including isotonic, hypertonic, and hypotonic. Learn more about crystalloids through helpful definitions and examples of tonicity.

Emulsion: Definition & Examples

4. Emulsion: Definition & Examples

An emulsion is a combination of non-soluble substances that are stabilized by the presence of a crucial material known as the emulsifier. Differentiate the concepts of hydrophobic and hydrophilic and explore examples of emulsions in culinary contexts.

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 the manipulation of compounds using chemical changes to separate the elements within. Discover the different types, and the basics of practicing this method.
