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.
