Ch 45: Chemical Equilibrium & Acid-Bases

About This Chapter

Watch the lessons in this chapter as you go over chemical equilibrium and acid-bases. Our instructors have built elaborate lessons that provide all the essential details about this chemistry topic, which will help you prepare for any in-class discussions, homework assignments, or upcoming exams.

Chemical Equilibrium & Acid-Bases - Chapter Summary

Develop your understanding of chemical equilibrium and acid-bases by taking the time to study this chapter. Each lesson provides a miniaturized study guide, allowing you to focus on the specifics of one area before advancing on to the next. In the lessons, you will discover all the major vocabulary words, definitions, and concept explanations associated with this topic, as well as examples and sample problems. When you complete the chapter, you will be prepared to:

  • Describe dynamic and chemical equilibrium
  • Identify the reaction quotient (Q) and the equilibrium constant (K)
  • Analyze the re-establishment and disruption of equilibrium
  • Check out the Arrhenius definition
  • Define bases and acids via the Bronsted-Lowry and Lewis method
  • Examine calculations for acid-based equilibrium

Our self-assessment quizzes provide an interactive way to measure your knowledge base for these chemistry topics. You can take the quizzes before or after you review the lessons. There are about five questions on each quiz, all of which have selected-response style questions. There is even a printable quiz worksheet available.

Equilibrium: Chemical and Dynamic

1. Equilibrium: Chemical and Dynamic

Learn the definition of chemical equilibrium and how it is dynamic. Discover what the equilibrium constant is and how it shows whether the reaction favors the reactants or products. Learn how chemists designate equilibrium in an equation and how they show the difference in reaction rate.

Equilibrium Constant (K) and Reaction Quotient (Q)

2. Equilibrium Constant (K) and Reaction Quotient (Q)

In this lesson, we will first define and explain the notion of a chemical equilibrium. Then, you'll learn about the equilibrium constant and reaction quotient. Finally, we'll round off the lesson with a couple of examples to solidify what you've learned!

LeChatelier's Principle: Disruption and Re-Establishment of Equilibrium

3. LeChatelier's Principle: Disruption and Re-Establishment of Equilibrium

Learn how Le Chatelier's Principle describes the disruption and re-establishment of equilibrium. Learn to explain the factors that disrupt equilibrium, such as concentration, temperature, and pressure. Learn how each of these factors affects a system in equilibrium.

The Arrhenius Definition of Acids and Bases

4. 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

5. 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.

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.
