Study Notes

Redox Reactions

Oxidation in a redox reaction is the process of losing one or more electrons by an atom, molecule, or ion.

Types of Redox Reactions

Electron-transfer redox reactions involve the transfer of electrons between species.
Atom transfer redox reactions involve the transfer of atoms or groups of atoms.

Examples of Atom Transfer Redox Reactions

A combustion reaction, such as the burning of methane (CH4), is an example of an atom transfer redox reaction.

Function of Oxidation Reactions

The main function of oxidation reactions in redox reactions is to facilitate the transfer of electrons.

Alternative to Oxides in Redox Reactions

Fluorides can serve the same function as oxides in redox reactions.
