Learn: Oxidation–reduction (redox) reactions - Khan Academy
An oxidation–reduction or redox reaction is a reaction that involves the transfer of electrons between chemical species (the atoms, ions, or molecules involved in the reaction). Redox reactions are all around us: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and reduction. Some examples of common redox ...
Simple redox reactions (video) - Khan Academy
An oxidation/reduction reaction (also known as a "redox" reaction) involves the transfer of electrons. The first definition of oxidation was indeed about oxygen, and meant that an element or compound gained oxygen atoms. However, we eventually came to understand that these chemical reactions frequently involved a transfer of electrons. When an atom loses electrons, it is oxidized. The atom ...
Learn: Balancing redox equations (article) | Khan Academy
The equations for oxidation-reduction reactions must be balanced for both mass and charge, which can make them challenging to balance by inspection alone. In this article, we’ll learn about the half-reaction method of balancing, a helpful procedure for balancing the equations of redox reactions occurring in aqueous solution.

Redox titrations (video) | Khan Academy
A redox titration is a titration in which the analyte and titrant react through an oxidation–reduction reaction. As in acid–base titrations, the endpoint of a redox titration is often detected using an indicator. Potassium permanganate (KMnO₄) is a popular titrant because it serves as its own indicator in acidic solution.

Introduction to cellular respiration and redox - Khan Academy
The reactions in which NAD + and FAD gain or lose electrons are examples of a class of reactions called redox reactions. Let's take a closer look at what these reactions are and why they're so important in cellular respiration.
AP®︎/College Chemistry - Khan Academy
Welcome to AP®︎/College Chemistry! In AP Chemistry, you'll learn about atomic structure, intermolecular forces and bonding, chemical reactions, kinetics, thermodynamics, equilibrium and more. To make sure you’re prepared with the fundamentals, we recommend completing high school chemistry before diving into AP Chemistry.
