Ch 19: Electrochemistry & Redox Reactions

About This Chapter

Improve your understanding of electrochemistry and redox reactions with this overview of battery cells, redox reactions, voltaic cells, and more. These short lessons are a helpful tool for students preparing for an exam or catching up on missed class time.

Electrochemistry & Redox Reactions - Chapter Summary

The lessons in this chapter provide an overview of electrochemistry and redox reactions. By going through these lessons, you can learn how to make a battery at home using lemons. You can also gain a better understanding of the transfer of electrons during redox reactions. After completing the chapter, you should be prepared to:

  • Discuss free energy and cell potential energy
  • Diagram an electrochemical cell
  • Explain the difference between batteries and fuel cells
  • Recall the structure of battery cells
  • Discuss cathodic protection of metal
  • Provide examples of redox reactions
  • Define single-displacement reaction

Each lesson comes with a brief quiz to ascertain how much of the content you can recall. You can study all of the lessons in sequential order or just go over the topics you need to review. Make the most of the chapter by printing the quiz in worksheet form to study offline.

Electrochemistry: Free Energy and Cell Potential Energy

1. Electrochemistry: Free Energy and Cell Potential Energy

Our modern lives are totally dependent on electricity. In this lesson, we learn about electricity spontaneously produced by electrochemical cells or batteries. We make the link between the potential energy they produce and Gibbs free energy.

Electrochemical Cells and Electrochemistry

2. Electrochemical Cells and Electrochemistry

Learn to identify the parts of and be able to describe an electrochemical cell, including the electrolyte, electrodes, anodes, and cathodes. Learn how to make a homemade lemon battery and how to diagram an electrochemical cell that will light a light bulb.

Types of Voltaic Cells: Batteries vs. Fuel Cells

3. Types of Voltaic Cells: Batteries vs. Fuel Cells

After completing this lesson, you will be able to explain what a voltaic cell is, and distinguish between two types of voltaic cells: batteries and fuel cells. A short quiz will follow.

Cathode and Anode Half-Cell Reactions

4. Cathode and Anode Half-Cell Reactions

Learn how to write electrode half-reactions for cathodes and anodes. Discover how to calculate cell voltage potential when given a table of standard electrode potentials. Learn how to prevent corrosion using redox concepts and how to protect metal by cathodic protection.

Redox (Oxidation-Reduction) Reactions: Definitions and Examples

5. 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.

Single-Displacement Reaction: Definition & Examples

6. Single-Displacement Reaction: Definition & Examples

There are so many chemical reactions that occur around us that we classify them into different types. In this lesson, we will discuss single-displacement reactions, one of the main types of chemical reactions.
