Whenever water or air is around iron for a while it can rust because the iron bonds to the oxygen forming iron oxide.
Answer 1: Salt and water especially if they are both present.Answer 2: Wrong. Water yes, but also oxygen, salt speeds up the reaction:Oxygen present in water and salt causes corrosion. Salt is hygroscopic in nature and it attracts the water. Water is required for corrosion and salt speeds up the process.
You need naked iron, in an environment containing oxygen (like most outside air, or water). Steel is carbon saturated steel. Oxygen can't easily bind with the iron elements in steel, as carbon has a stronger bond, and even if an oxygen atom would pull out another atom out of the steel it would be a carbon atom, not an iron one.
Rust is an iron oxide compound. There are several different iron oxides that make up rust.
Rust is cause by the oxidation of Iron. Basically, when Iron reacts with Oxygen, Rust is fromed. 2Fe2 + 3O2 ---> 2Fe2O3 (Rust) For this reason, it is only things made out of Iron that can rust. I hope I helped! :)
Iron rusts when it comes into contact with oxygen and water. The presence of these two elements, along with iron, is necessary for rust to form.
Iron rusts when it reacts with oxygen in the presence of water to form iron oxide. The compound needed for iron to rust is iron oxide, which is commonly known as rust.
Oxygen gas is needed for iron to rust. When iron is exposed to oxygen and moisture in the air, a chemical reaction occurs that forms iron oxide, which is known as rust.
There are various chemicals that make things rust and a good example is muriatic acid. Rust occurs when iron is oxidized.
soda does not make iron rust ...
Iron and iron alloys.
Oxygen reacts with the iron to make it rust.

Iron oxide or rust
The iron would react with the oxygen in the water to make iron oxide, or rust.
rust is oxidized iron basically that means FeO or Iron Oxide. this occurs on steel, as steel is iron and carbon (amongst other things) it is the Iron that oxidizes to make the rust.
