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
