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.

Zusammenfassung der Kapitel (Chapter Summaries)
The report begins with an introduction outlining the objectives and methodology of the experiment. It describes the preparation of the iron nails, the three types of water used, and the experimental setup. The report details the visual observations made throughout the experiment, documenting the corrosion process in each water type, including the formation of rust and other visual changes.
The report then delves into a discussion of the observed corrosion phenomena, exploring the underlying chemical processes involved. It examines the influence of factors such as pH, temperature, and the presence of dissolved gases on the corrosion rates of iron in each water type. The chapter further discusses the formation of protective layers and their role in mitigating corrosion.
