Redox reactions or reduction and oxidation are reactions in which electrons are simultaneously transferred from one chemical species to another. This episode begins with exploring this concept, including an in-depth look at oxidizing and reducing agents and the factors determining a compound's effectiveness as an oxidizing agent. 

It also covers the oxidation states of molecules and functional groups, common redox reagents in organic chemistry, and the role of redox in biological systems. The episode also addresses numerical concepts from general chemistry related to redox, such as determining oxidation numbers and understanding electrochemical cells.
