Ch 24: Acid & Base Definitions

About This Chapter

This chapter can help you learn more about acids and bases in preparation for an exam. The lessons are a convenient way catch up on topics like titrations, buffers, and solutions and can be accessed on any computer or mobile device.

Acids & Bases Definitions - Chapter Summary

Get up to speed on acids and bases with these engaging lessons. Review various theories related to acids and bases, including the Arrhenius, Bronsed-Lowry, and Lewis theories. You can explore acidic and basic salt solutions, amphiprotic substances, and acid-base reactions. Finally, you will learn about the pH scale and how to measure the pH of a buffered solution. After you are done, you will be able to:

  • Define acids and bases
  • Discuss the early theories of acids and bases
  • Recognize what conjugate acids and bases are
  • Describe how acids and bases can be neutralized
  • Explain how titration curves work for strong and weak acids and bases

The interactive quiz available with each lesson lets you quickly review what you have just learned. Both the lessons and quizzes can be accessed whenever you like, using your phone, tablet or computer. Your Dashboard allows you to track your progress through the chapter no matter where you study.

Early Theories of Acids & Bases

1. Early Theories of Acids & Bases

In this lesson, you will learn about the history of acids and bases. Study the progression of the different theories of acids and bases, starting in the 1700s and leading up to today.

The Arrhenius Definition of Acids and Bases

2. The Arrhenius Definition of Acids and Bases

In this lesson, you will learn the definition of Arrhenius acids and bases, discover some of their chemical properties and learn some examples. You will also learn about the difference between strong and weak Arrhenius acids and bases.

The Bronsted-Lowry and Lewis Definition of Acids and Bases

3. The Bronsted-Lowry and Lewis Definition of Acids and Bases

Learn the Bronsted-Lowry and Lewis definitions of an acid and base. Discover how these theories differ from each other and from the Arrhenius theory of an acid and base. Learn how to identify an acid in terms of proton donation and a base as a proton acceptor, and explain what a conjugate acid or base is.

What is a Conjugate Acid? - Definition & Examples

4. What is a Conjugate Acid? - Definition & Examples

Explore this lesson to learn about conjugate acids, how they are different from other acids, and where to find them in a given acid-base equation. Then, apply what you have learned, in this lesson, to examples involving conjugate acids.

Conjugate Base: Definition & Overview

5. Conjugate Base: Definition & Overview

In this lesson, you'll learn about conjugate bases in chemistry and where they come from. You'll also learn about their relationship to acids and see how acid-base reactions work.

Acidic & Basic Salt Solutions: Explanation & Examples

6. Acidic & Basic Salt Solutions: Explanation & Examples

In this video lesson, you will learn how to tell if a salt solution is acidic, basic, or neutral. You will find out how to recognize the effect of individual ions in solution and how they can change the pH. A short quiz will test your knowledge.

Amphiprotic Substances: Definition & Examples

7. Amphiprotic Substances: Definition & Examples

In acid-base chemistry, did you know water is a very common amphiprotic substance? Explore this lesson to learn what amphiprotic is and identify different compounds classified as amphiprotic.

Neutralization and Acid-Base Reactions

8. Neutralization and Acid-Base Reactions

From this lesson, you will understand the neutralization process between acids and bases. Learn how a hydroxide ion from a base reacts with a hydronium ion from an acid to neutralize each other and form water. Discover what conjugate acids and bases are and what the definition of amphoteric is.

Acid-Base Buffers: Calculating the pH of a Buffered Solution

9. Acid-Base Buffers: Calculating the pH of a Buffered Solution

Learn what a buffer is, how it works, and why we benefit from having our blood buffered. Learn how to calculate the pH of a buffered solution before an acid or base is added and how the pH changes after an acid or base is added.

Titration of a Strong Acid or a Strong Base

10. Titration of a Strong Acid or a Strong Base

Discover what titration is and how to calculate the concentration of an acid or base that has been titrated to equivalence. Learn the meaning of titrant, standard solution and equivalence point. Study titration curves and learn how to determine pH during any point of a titration between a strong acid and strong base.

Titrations with Weak Acids or Weak Bases

11. Titrations with Weak Acids or Weak Bases

Learn about titrations with weak acids or weak bases in this lesson. Study their titration curves and learn about some of their important characteristics. Learn how to calculate pH during titrations involving weak acids and strong bases.
