In the rusting experiment why is it important to cover the boiled water with oil?

Covering the boiled water with oil helps create an oxygen-free environment in the container. This prevents the water from getting oxidized during the rusting experiment, allowing the experimenter to analyze the impact of exposure to water on the rusting process.

Which liquid prevents rusting?

Any one organic liquid immiscible with water as hexane, benzene , mustard oil may prevent the rusting of metals.Nails, iron, and similar metals rust when they contact oxygen and water, although this reaction is very slow. When submerged in water, (which is 88.7% oxygen, compared to air which is only 20% oxygen and 78% nitrogen) these metals will rust considerably faster (although still slowly).Your best option would be something like oil, which doesn't mix with water. Better yet, simply leaving the nails in a dry location will prevent rust from occurring potentially for years or decades.


What is done to stop bridges from rusting?

Metal comes in contact with oxygen. That's the main reason that many mechanics wipe down their older metal tools with oil (WD-40). The coat of oil prevents air from contacting the metal. That's why they spend much more than $100,000 to paint a bridge. The coat of paint saves them. H2O, water, has the same effect on metal.
