Basic Concept: All chemical reactions involve electrons. When an electron is lost or gained it is known as a Redox reaction (not the bubble bath as that's Radox).
The details: Two different things happen in a reaction. They are oxidation and reduction both originally used to describe a reaction involving oxygen.
However in the modern day oxidation and reduction have a wider definition in the terms of electrons of all the elements as oppose to just oxygen.
So what do they mean? Well oxidation is the loss of electrons in a reaction. This is in contrast to reduction which is the gaining…
