3. Redox Reactions

Metals are fantastic materials to use for structural components or for decoration. Sometimes, however, metals react when they are exposed to air, water, or other substances. In some situations the reaction decreases the performance of the object. In extreme cases, metal fatigue or failure can have drastic consequences, such as when metal fatigue causes a large structure to collapse.

 

A great deal of scientific work and technological development has gone into studying metals and into preventing metal corrosion. If you consider how many of the objects you use involve metals, you will understand why so much attention is placed on understanding corrosion.

 

In this unit you will investigate the following questions:

  • What properties of metals make them popular choices in the construction and production of materials?
  • How can an understanding of corrosion allow for better selection of materials and for development of methods that reduce material damage?
