Redox Reactions

Redox reactions are fundamental chemical processes involving the transfer of electrons between two species. Oxidation is characterized by an increase in oxidation number and the loss of electrons, while reduction involves a gain of electrons and a decrease in oxidation number.

Redox Reactions

Redox Reactions

Reduction

Example: Cu^2+ 2e^- ----> Cu (copper is reduced from +2 to 0)
Decrease in oxidation number
Gain of electrons

Oxidation

Example: Fe^2+ + 2e^- ----> Cu (iron is oxidized from 0 to +2)
Increase in oxidation number
Loss of electrons

Redox Reaction Example

Zn ---> Zn^2+ + 2e^-
Cu^2+ ---> Cu

Zn + Cu^2+ ---> Zn^2+ + Cu
