Corrosiveness of Different Types of Water

The corrosiveness of three different types of water was analysed through an experiment carried out with iron nails immersed in a bath for a period of 25 days. The types of water used during the experiment were respectively synthetic seawater, mineral water and sparkling water. The iron nails immersed in a bath of both synthetic seawater and mineral water suffered a corrosive attack characterized by the formation of reddish brown flakes which have adhered the surface of the iron nails. Whilst, on the other experiment, the iron nail immersed in the sparkling water suffered a very minimal corrosive attack owing to the formation of a protective layer which prevented the underlying steel from further dissolution.
