Ch 12: Electrochemistry for the MCAT: Help and Review

About This Chapter

The Electrochemistry chapter of this Medical College Admission Test (MCAT) Help and Review course is the simplest way to master electrochemistry. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of electrochemistry.

Who's it for?

Anyone who needs help preparing for the science section of the MCAT exam will benefit from taking this course. You will be able to grasp the subject matter faster, retain critical knowledge longer and earn better grades. You're in the right place if you:

  • Have fallen behind in understanding how chemical energy is converted to electrical energy.
  • Need an efficient way to learn about electrochemistry.
  • Learn best with engaging auditory and visual tools.
  • Struggle with learning disabilities or learning differences, including autism and ADHD.
  • Experience difficulty understanding your teachers.
  • Missed class time and need to catch up.
  • Can't access extra MCAT science preparation resources at school.

How it works:

  • Start at the beginning, or identify the topics that you need help with.
  • Watch and learn from fun videos, reviewing as needed.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Submit questions to one of our instructors for personalized support if you need extra help.
  • Verify you're ready by completing the Electrochemistry chapter exam.

Why it works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the Electrochemistry chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any relevant question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students will review:

In this chapter, you'll learn the answers to questions including:

  • What are the parts of an electrochemical cell?
  • How do cell potential energy and free energy work in electrochemistry?
  • Why do cathode and anode half-cell reactions occur?
  • How do electrolyte and non-electrolyte solutions differ from each other?
  • What is the relationship between Faraday's law and electron flow?
  • How do redox reactions occur at an electrode?
  • What are the major components of galvanic cells?

5 Lessons in Chapter 12: Electrochemistry for the MCAT: Help and Review
Electrochemical Cells and Electrochemistry

1. 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.

Electrochemistry: Free Energy and Cell Potential Energy

2. 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.

Cathode and Anode Half-Cell Reactions

3. 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.

Solutions, Electrolytes and Nonelectrolytes

4. 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.

Nernst Equation: Example & Calculator

5. 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.
