Overview
For this discussion I would like you to find a metal object which had gone through oxidation. Take a picture of it, explain what kind of element the object is made out of and provide a chemical reaction explaining the oxidation process.
Below you can find a list of examples, but feel free to chose any metal which can be oxidized.
Tarnish found on silver teapots, trays, and jewelry.
Copper carbonate, or patina, the corrosion that causes copper to turn green.
- Discolored spots that appear on brass.
- Aluminum oxide, which forms on aluminum.
- Chromium oxide, which forms on the outside layer of stainless steel.
- Iron oxides on the surface of the steel.
