Ch 25: Electrochemistry & Voltaic Cells

About This Chapter

You have the chance to learn more about electrochemistry and voltaic cells through this chapter's short lessons and self-assessment quizzes. Topics covered include electrolysis, the Nernst equation, Faraday's Law, and cathode and anode half-cell reactions.

Electrochemistry & Voltaic Cells- Chapter Summary

Going through each lesson in this chapter, you will be able to review and learn more information about electrochemistry and voltaic cells. Information on free energy and cell potential energy is provided, and you'll be able to examine how voltaic and electrolytic cells differ. Another lessons explores Kohlrausch's law and how it explains conductivity. When you're done with this chapter, you should be prepared to:

  • Review the process of electrolysis
  • Identify information about Faraday's law of electromagnetic induction
  • Recall the relationship between free energy and cell potential energy
  • Understand the two types of voltaic cells
  • Discover how to calculate cell voltage potential
  • Explain the components of the Nernst equation
  • Discuss the importance of electrochemical cells
  • Explore Kohlrauschs' law

Our lessons are interactive and engaging. They help you quickly learn material on topics that can be difficult to understand. After you have gone through the lessons, you can use the quizzes to check your knowledge and comprehension of the lessons. These quizzes give you immediate feedback so you can be sure what your strengths and weaknesses are.

What is Electrolysis? - Definition, Process & Facts

1. 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.

Faraday's Law of Electromagnetic Induction: Equation and Application

2. Faraday's Law of Electromagnetic Induction: Equation and Application

Electromagnetic induction allows us to induce voltage with the movement of a magnetic field. Credited to Michael Faraday, this discovery was not only groundbreaking at the time, but it has since led to many applications in everyday life.

Electrochemistry: Free Energy and Cell Potential Energy

3. 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.

Types of Voltaic Cells: Batteries vs. Fuel Cells

4. 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

5. 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.

Nernst Equation: Example & Calculator

6. Nernst Equation: Example & Calculator

In this lesson, you'll find out what the battery in your cell phone has to do with the Nernst equation. Through the use of easy-to-understand explanations, you'll have the chance to decode the equation and see how it works under a set of conditions.

The Differences Between Voltaic & Electrolytic Cells

7. The Differences Between Voltaic & Electrolytic Cells

Voltaic and electrolytic cells are very similar, but there are some key differences. In this lesson, learn about both of these electrochemical cells and their importance to everyday life.
