Learn about oxidation and reduction through a free educational video on Khan Academy, covering the basics of redox reactions.
Khan Academy
By assigning oxidation numbers to the atoms of each element in a redox equation, we can determine which element is oxidized and which element is reduced during the reaction. In this video, we'll use this method to identify the oxidized and reduced elements in the reaction that occurs between I⁻ and MnO₄⁻ in basic solution.

Simple redox reactions - 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.
Khan Academy
If we reverse a redox reaction, we change the direction electron is moving. If it begins as a reduction reaction where an electron is gained, reversing the reaction will make it an oxidation reaction where an electron is lost.
