Redox reactions and electrochemistry

This course is a part of AP®︎ Chemistry, a 15-course Topic series from Khan Academy.

In this tutorial we will learn about oxidation-reduction (or redox) reactions and how they can be used in galvanic cells and electrolysis.

This course contains 6 segments:

Oxidation-reduction reactions

Oxidation and reduction are powerful ideas for thinking about how charge is transferred within a reaction. As we'll see, it is something of a hypothetical, but it is, nonetheless, very useful.

Galvanic cells

Batteries power much of our lives (literally). In this tutorial, we'll use our knowledge of oxidation and reduction to understand how Galvanic/Voltaic cells actually work.

Standard cell potentials

An introduction to calculating cell potentials at standard state.

Electrochemistry, thermodynamics, and equilibrium

Relating the cell potential to the equilibrium constant K and Gibbs free energy.

Cell potentials under nonstandard conditions

Calculating the cell potential when operating at nonstandard conditions.

Electrolytic cells and electrolysis

An introduction to electrolytic cells and electrolysis
