What happen when iron is exposed to air?
If an iron nail is exposed to air for a long time it reacts with the water vapour (moisture) and oxygen present in the atmosphere and a reddish-brown powdery coating is formed on it known as RUST (Fe2O3.xH2O) .
What rusts faster aluminium or carbon steel?
Since aluminum cannot rust ('rust' is a specific term for the corrosion of iron), carbon steel will be faster. Althpough an oxide coat forms on both aluminum and steel, the oxides are of a different nature. The iron "rust" is a pervious coating which allows water to be held against the metal and oxygen to enter and react with the wet metal, aluminum oxide is an impervious layer which protects the metal from further decomposition,
Is pewter waterproof?
No it will not rust as it doesnt have iron in it, but it may corrode and turn black over time
Is rust intensive or extensive?
It could be both. Rust is the result of the oxidation of metallic Iron. if exposed to air and water the rust can be extensive over the exposed surface and if the surface has been exposed for a long time the rust can be quite thick, intensive.
What changes occur when a nail rusts?
when a nail rusts it is because the nails are made of iron the rusts forms when the iron nail comes in contact with rain and oxygen at the same time which forms rust over time more water comes in contact with the nail and more rust is formed the word equation for this change: Iron+Water+Oxygen-->iron oxide(rust)+Hydrogen The chemical equation for this change 2Fe+H2O+O-->Fe2O3+H hope this helped
How do you rust iron?
by leaving it there for a lond time like 2 min Iron + oxygen = iron oxide (rust) Wetting it seems to accelerate the process.
Will Cast Iron Patio Set Rust over Time?
Cast iron furniture will rust over time. However, one can buy a specialized brush set intended to remove rust from furniture.
What ways can rust harm iron?
Iron structures and objects are destroyed in time.
Can steel wool rust?
Yes, steel wool can rust. Steel is a ferrous material, meaning it is mostly iron. Rust is iron oxide. Thus, if you keep steel wool wet, it will certainly rust. Adding an oxidizer will increase the rate of this process as well.
Can soapy water rust iron?
soapy water does make nails rust because of the soap mixed with water are two different types of liquids which also makes it faster to rust
Do all metals rust?
Only metals containing iron rust. Other metals, over time, corrode.
What is rust and how fast does rust form in a bowl of water on a nail?
Fe2O3 Iron Oxide time is varying but if the metal is hotter rust occurs faster.
What happen when iron is exposed to air?

Can water iron filling be dissolved in the water?
Iron filings can't be dissolved in water, but, over time iron filling in water will rust away.
Why isn't there rust in painted areas of the car?
Rust is oxidized iron. When iron is exposed to the oxygen in air or water over a period of time, the iron oxidizes. If it is exposed long enough, the iron turns red, grainy and soft and becomes rust. Rust can be removed by sanding or grinding. For a car, this requires multiple sandings with various grits of sanding compound. This is followed by primer, then by paint before new rust has time to set in. If the rust has eaten a hole in the metal, then Bondo is applied first. Once the primer and paint are dry, the metal is protected. Hope that answered your question. Princess

Why when iron is placed in acid does it not rust to start with but it will rust after 2 or 3 days?
Because it takes time for oxygen to separate from acid molecules and react with iron it depends on the type of acid and the pH of that acids. If it's a very weak acid it can take some weeks.. if it's a strong acid, like H2SO4 sulfuric acid, it can take seconds..
