Redox Reaction Example

Oxidation Half-Reaction

Reduction Half-Reaction

Over all Balanced
Equation

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

Cu^2+ ---> Cu

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

Oxidation

Reduction

Gain of electrons

Decrease in oxidation number

Example:
Cu^2+ 2e^- ----> Cu
(copper is reduced from +2 to 0)
