This video is an introduction to oxidation reduction reactions. We often abbreviate oxidation and reduction, so we just call these redox reactions for short. So, what is an oxidation reduction or redox reaction? Here's a quick definition: In oxidation reduction reactions, electrons move between atoms. Check out this diagram. We have atom A and atom B, and there's an electron moving out of atom A into atom B. So, this is definitely an oxidation reduction reaction because there's an electron moving between the atoms. Now, we can describe the movement of this electron using the words oxidation and reduction. So, let's learn specifically what both of these mean. Reduction is a gain of electrons. I know this seems kind of confusing because usually when you have a reduction of something, you have less of it. We'll talk later about why a gain of electrons is called a reduction, but anyway, reduction is a gain of electrons and then oxidation, which is a loss of electrons. So, we got reduction and oxidation. What's happening to atoms A and B over here? Well, atom A is giving up one of its electrons. It's losing an electron, so atom A oxidation is taking place. Atom B is receiving an electron. It's gaining an electron, so it atom B reduction is taking place. Now, we can modify these words slightly to come up with terms we use to describe what's happening to the ABS. Atom A is undergoing oxidation, so we can say that atom A is being oxidized. Atom B is undergoing reduction, so we can say that atom B is being reduced. So, we got oxidation (oxidized) and reduction (reduced). The big picture here is that reduction is a gain of electrons and oxidation is a loss. So, I don't know about...
