redox
Electron transfer reaction
Redox is a type of chemical reaction in which electrons are transferred between substances, causing one to be oxidized (lose electrons) and another to be reduced (gain electrons).
The term blends reduction and oxidation, which always occur together.
Redox reactions power batteries, cause metals to rust, and drive cellular respiration.
The redox potential of a solution determines which reactions can occur.
