Oxidation and
Reduction
Meaning- reactions in which there’s a simultaneous transfer
of electrons from one chemical species to another
-composed of two different reactions: oxidation
(a loss of electrons) and reduction (a gain of electrons).
The electrons that are lost in the oxidation
reaction are the same electrons that are gained in the reduction reaction.
These two reactions are commonly called half-reactions; the overall
reaction is called a redox (reduction/oxidation) reaction.There are three definitions you can use for oxidation:
The loss of electrons The gain of oxygen The loss of hydrogen
The gain of
electrons
The loss of oxygen
The gain of
hydrogenvideo about redox:
