Rust is porous, it allows air & water to get to the metal underneath.

∙ 7y ago
Rust is actually formed when iron is exposed to oxygen and moisture, causing a chemical reaction that produces iron oxide. This iron oxide layer is porous and allows further oxidation of the iron beneath, ultimately leading to rusting. So, rather than protecting iron, rust is a breakdown of the iron itself.

Can copper pennies rust?
Copper does not rust, but it can develop a patina or greenish tarnish when exposed to air and moisture over time. This patina can actually help protect the copper from further corrosion.
Why doesn't nail rust in milk?
Nails do not rust in milk because milk does not contain the elements necessary for the rusting process to occur. Rusting requires moisture, oxygen, and iron to create iron oxide, which is what we commonly refer to as rust. Milk lacks the oxygen component necessary for rusting to happen.
Is rust an element?
Rust is not an element, but rather iron oxide, a compound formed from the reaction of iron and oxygen.
Is rust a compound?
yes rust is a compound because it is a formed by the reaction between Iron and Oxygen. These two react to give Iron Oxide which is called as rust. Edited by Dr.J. - The iron oxides that is rust is the Fe2O3 variety.
What 2 things are needed to make iron rust?
Iron and oxygen are needed for iron to rust. When iron is exposed to moisture and air, a chemical reaction occurs where the iron oxidizes to form iron oxide, which is known as rust.
What cause zinc to rust?
Zinc doesn't rust; zinc protect iron (and alloys) from rusting.
What process is done to protect the iron surface from rust?
Galvanizing
Does paint protect iron from ruse?
Yes, paint can protect iron from rust by acting as a barrier between the iron and moisture in the air. However, if the paint gets chipped or scratched, it can expose the iron to oxygen and water, leading to rust formation. Regular maintenance and touch-ups are important to ensure continued protection.
Why doesn't sprite rust iron?
it probably will over a long time, but it doesnt have much oxygen cause the water is diluted so it wont rust quickly
Can graphite rackets rust?
No they will not get rust they are not iron to get rust. only iron get rust.
Can copper pennies rust?
Copper does not rust, but it can develop a patina or greenish tarnish when exposed to air and moisture over time. This patina can actually help protect the copper from further corrosion.
What types of metals do not rust?
I think that srtonger metals like gold do not rust. I also think that some metals, when combined with others do not rust, like when you combine iron with aluminum, it doesn't rust. By definition, the only metals that rust are iron and iron alloys. Even so, not all iron alloys rust. Stainless steel (an iron alloy) does not rust. Gold doesn't rust, in that it doesn't combine with oxygen from the atmosphere to form a surface of gold oxide. But it can tarnish, that is, for a thin transparent darker layer to form on the surface. however steel will rust. to protect a metal from rusting you must galvanzie it or paint. for example to galvanzie iron you must use a metal higher in the electrochemical series like zinc. this will protect it from rusting.
How do you protect cast iron chairs from getting rust?
Wax them or coat them with oil to keep moisture away.
Why iron does not rust?
Iron does rust by reacting with oxygen.
Which liquids rust faster?
Liquids do not rust, iron does, rust is Hydrated Iron (III) oxide, so the only substance which can rust iron is water
Why does iron not rust when in contact with Mg?
Iron does not rust when in contact with magnesium because magnesium is more reactive than iron. The magnesium will undergo oxidation, sacrificing itself to protect the iron from corrosion. This forms a protective layer on the iron surface, preventing it from coming into contact with oxygen and water, which are needed for rusting.
What does rust and iron form?
Rust is an iron oxide, Fe2O3.
