Ch 9: Chapter 9: Acids, Bases & Salts - Holt Physical Science With Earth & Space Science

About This Chapter

The Acids, Bases & Salts chapter of this Holt Science Spectrum - Physical Science with Earth and Space Science Textbook Companion Course helps students learn the essential lessons associated with acids, bases and salts. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Acids, Bases & Salts textbook chapter.

How It Works:

  • Identify the lessons in the Acids, Bases and Salts chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover acid, base and salt topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Acids and Bases

1. 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.

Solutions, Electrolytes and Nonelectrolytes

2. 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.

Acidic, Basic & Neutral Solutions: Determining pH

3. Acidic, Basic & Neutral Solutions: Determining pH

After watching this video, you will be able to explain the difference between acidic, basic, and neutral solutions and explain the concept of pH. A short quiz will follow.

The pH Scale: Calculating the pH of a Solution

4. 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.

Neutralization and Acid-Base Reactions

5. 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.

What is Salt in Chemistry? - Definition & Formula

6. What is Salt in Chemistry? - Definition & Formula

What exactly do we mean by 'salt' in chemistry? Learn more about the definition, chemical, and physical properties and how we can easily figure out the chemical formula of many salts. Test what you have learned with a quiz.

Home Products wiith Acids, Bases & Salts

7. Home Products wiith Acids, Bases & Salts

After completing this lesson, you will be able to explain what acids, bases and salts are, and give some examples of products in the home from each category. A short quiz will follow.
