Redox reaction

Definition

noun

A chemical reaction involving both reduction and oxidation, which results in changes in oxidation numbers of atoms included in the reaction.


Supplement

Redox reaction involves oxidation where there is an increase in oxidation number, and reduction where there is a decrease in oxidation number. It is involved in many important biological processes, such as cellular respiration and photosynthesis. In cellular respiration, for instance, redox reaction occurs when glucose is oxidized to carbon dioxide whereas oxygen is reduced to water.


Variant: oxidation reduction reaction

See also: reduction, oxidation.

separate redox reaction into its componet half-reactions

I have to write the oxidation and reduction reactions for 3O2 + 4Fe---> 2Fe2O3 As the oxidation-half reaction I have 4Fe--->4Fe^3+ + 12 e- As the reduction half reaction I have 3O2 + 12e- ---> 6O^2- are my answers correct? Thank you!
