Redox reactions as electron transfer – basic principles
How it works
Redox reactions are chemical reactions in which electrons are transferred from one reaction partner to another. In the process, the electron-donor particle is oxidized (gives off electrons) and the electron-acceptor particle is reduced (takes up electrons). Oxidizing agents take up electrons, reducing agents give off electrons. The oxidation number helps to recognize electron transfers. Typical examples are the reaction of metals with oxygen or the reaction of iron with copper ions.
Note
In a redox reaction, electron transfer always takes place: The reducing agent gives off electrons (oxidation), the oxidizing agent takes up electrons (reduction).

An example
Which statement correctly describes a redox reaction?
A redox reaction is a chemical reaction in which electrons are transferred from one substance to another. That is correct because the definition of redox reactions includes electron transfer.
