redox
n. uncountable C1 Advanced re·dox
n. a chemical process where one substance loses electrons and another gains them. This happens in many natural processes, like how batteries work or how your body breaks down food.
n. a chemical reaction involving the transfer of electrons between two species, resulting in a change in their oxidation states. Often used as a shortened form of 'oxidation-reduction'.
The battery works through a redox reaction.
In a redox reaction, the substance that loses electrons is oxidized, while the one that gains them is reduced.
Understanding the specific redox potentials of different metals allows engineers to design more efficient electrochemical cells for renewable energy storage.
Shortening of reduction and oxidation.
