Part IV - Everyday Examples

Oxidation-reduction reactions have many far-reaching applications in our lives. Some of these applications are so common, that we take them for granted; others are not so obvious. The following are just a few examples of oxidation-reduction reactions.

• Bleaching Agents
• Photosynthesis
• Metabolism
• Nitrogen Fixation
• Electrochemistry
• Combustion of Fuels
• Refining Metal Ores
• The "Dry Cell" Battery
• Photo-oxidation (Photogray ® Glasses)
• Corrosion
