About This Chapter
Ionic Theory & Chemical Reactions - Chapter Summary
While going through these lessons, you'll deepen your understanding of ionic theory and chemical reactions. You'll review topics like how to identify a base as a proton acceptor. This chapter can also help you understand how electrolysis facilitates the decomposition of substances. After reviewing the lessons, you should be ready to:
- Describe the formation of ions using the octet rule
- Explain the process of electrolysis
- Discuss Arrhenius, Bronsted-Lowry, and Lewis definitions of acids
- Define dissociation constant and auto-ionization of water
- Explain why the hydrolysis reaction is used to break sucrose into glucose and fructose sugar
- Analyze the neutralization process between acids and bases
- Provide examples of redox reactions
These lessons are filled with key details, and our expert instructors provide helpful examples. Vocabulary words are highlighted in bold for quick reference. A multiple-choice quiz is available to test your knowledge after each lesson, and the quizzes can be printed for use as offline worksheets.
1. Ions: Predicting Formation, Charge, and Formulas of Ions
Learn how ions are formed using the octet rule. Use the periodic table to predict the charge an atom will have when it becomes an ion. Learn whether an ion is a cation or anion and how to write the formula depending on what charge the ion has.
2. What is Electrolysis? - Definition, Process & Facts
Did you know electrolysis is able to facilitate the decomposition of substances? In this lesson, you'll learn more about the process of electrolysis, after which, you can test your own expertise on the subject with a short quiz.
3. 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.
4. 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.
5. Dissociation Constant and Autoionization of Water
Learn the meaning of auto-ionization of water, sometimes called self-ionization, where water acts as a proton donor and acceptor to form both hydronium and hydroxide ions. Learn what the auto-ionization constant is and how to use it to determine the concentration of either hydroxide or hydronium ions in a solution when given the other value.
6. Hydrolysis: Definition, Reaction, Equation & Example
Have you ever wondered why the hydrolysis reaction is used to break table sugar, or sucrose, into glucose and fructose sugars? Continue reading to learn about the hydrolysis reaction, including examples of different types of hydrolysis reactions.
7. 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.
8. Redox (Oxidation-Reduction) Reactions: Definitions and Examples
This short video will explain oxidation-reduction reactions, or redox reactions for short. The focus is on how electrons are transferred during redox reactions. Learn some neat mnemonic devices to help you remember when an atom is oxidizing or reducing.
