|Electroplating: Oxidation-Reduction Reactions
Electrons are the currency in electrochemical reactions. Electrochemical reactions depend on transfer of electrons from one atom, ion, or molecule to another. Sometimes these electron transfers can be externally forced, and sometimes they are spontaneous
Each field of study or work develops its own language. Chemistry is no exception. We have words that we use to tell whether an atom, ion, or molecule steals or gains an electron (thus reducing its charge or moving the overall charge in the negative direction), or if it gives up an electron, thus moving its overall charge in the positive direction.
These words are ... Reduction and Oxidation.
Reduction: Gain of an electron, moving the overall charge in the negative direction, or reducing it.
Oxidation: Loss of an electron, moving the overall charge in the positive direction.
