Principle

Some metals are found to be quite stable in air, although they should be extremely unstable according to their position in the electrochemical series. The most well known metal of this type is aluminium. It has a standard potential E0 of -1.66 V. It is therefore far more a base metal than zinc (E0 = 0.7628 V) or even iron (E0 = 0.409 V).
In this experiment, the student investigates why the base metal aluminium is so resistant against the influence of weathering.
