Ch 29: TExES Physical Science 6-12: Acids & Bases in Chemistry

About This Chapter

Rediscover or learn new information about acids and bases. The video lessons and quizzes will focus on concepts to help you answer questions on the Texas Examinations of Educator Standards (TExES) Physical Science 6-12 exam.

TExES Physical Science 6-12: Acids & Bases in Chemistry - Chapter Summary

This chapter's lessons provide you with the opportunity to study the properties, calculations, bonding principles and definitions of acids and bases. Reviewing this material can help you prepare you to correctly answer relevant questions when you take the TExES Physical Science 6-12 exam. After completing the chapter, you should be able to:

  • Define acids and bases based on the Arrhenius, Bronsted-Lowry and Lewis definitions
  • Calculate the pH of a solution
  • Discuss weak bases, weak acids and buffers
  • Predict precipitates and net ionic equations
  • Calculate the Ka or Kb of a solution
  • Find the pH of a buffered solution
  • Detail the titration of a strong acid, strong base, weak acid or weak base

These complex topics are explained in a simple and straightforward narrative using illustrations and examples to support the text. You can gauge what you've learned by taking the self-assessment quizzes as many times as needed to gain proficiency in this area.

The Arrhenius Definition of Acids and Bases

1. 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

2. 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.

The pH Scale: Calculating the pH of a Solution

3. The pH Scale: Calculating the pH of a Solution

Learn the history of the pH scale, how to describe it and why it is used by scientists. Discover how to calculate the pH of an acid or base solutions given either the hydroxide ion concentration or the hydronium ion concentration. Learn how to start with the pH and calculate the hydroxide and hydronium ion concentrations.

Weak Acids, Weak Bases, and Buffers

4. Weak Acids, Weak Bases, and Buffers

This lesson covers both strong and weak acids and bases, using human blood as an example for the discussion. Other concepts discussed included conjugate acids and bases, the acidity constant, and buffer systems within the blood.

Precipitation Reactions: Predicting Precipitates and Net Ionic Equations

5. Precipitation Reactions: Predicting Precipitates and Net Ionic Equations

Learn what a precipitate is and predict when it will form in an aqueous chemical reaction, usually a double-replacement reaction. Learn what an ionic equation is, how it differs from a net ionic equation and how to write a net ionic equation.

Acid-Base Equilibrium: Calculating the Ka or Kb of a Solution

6. Acid-Base Equilibrium: Calculating the Ka or Kb of a Solution

In this lesson, you will review acid and base strength and acid and base dissociation. You will then learn what acid and base dissociation constants (Ka and Kb) are, what they mean, and how to perform calculations involving them.

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

7. 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

8. 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

9. 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.
