They should see that the nails in tubes 2 and 4 do not rust. The nail in tube 3 rusts the most. From this they should be able to conclude that water and air (actually oxygen in the air) are essential for rusting. Salt can increase the rate of rusting.
26 de mar. de 2020 · Learn how water and oxygen react with iron to form rust, a porous and crystallized iron oxide. Explore the electrochemical and redox reactions involved in rusting and how salt can speed up the process.
11 de abr. de 2018 · Learn why nails rust and how different liquids affect the rusting process. Follow the steps to conduct your own experiment and compare the results of nails in oil, water, vinegar and detergent.
Try this class practical or demonstration to test and assess a variety of methods for preventing rust. In this experiment, students protect iron nails using painting, greasing and sacrificial protection. The nails are placed in test tubes and covered with corrosion indicator solution. This contains gelatine and so sets to a jelly-like consistency.
Declan Fleming presents an experiment to illustrate the electrochemistry of rusting. Most courses studied by 16–18 year olds require them to be familiar with the process of rusting from an electrochemical perspective. However, many rusting demonstrations take a long time to produce any results without providing much information about the ...
