oxidation
When many materials containing iron are exposed to oxygen and water, they undergo a chemical reaction known as oxidation, leading to the formation of rust, primarily iron oxide (Fe2O3·nH2O). This process can weaken the structural integrity of the iron-containing materials over time, resulting in corrosion. The presence of electrolytes, such as salt, can accelerate this degradation. Proper protective measures, like painting or galvanization, can help prevent rust formation.
Oxidation is mostly what occurs and rust is the by product but,this can take decades and even centuries
Oxidation happens.
ya that is right
Lots of materials oxidize when exposed to oxygen; water is not strictly necessary for this to occur.Aluminium, for example, oxidizes almost immediately when exposed to oxygen. You've probably never touched aluminium; anything aluminium you've picked up had a thin, transparent layer of alumina (aluminium oxide) covering and protecting the metal underneath.
Iron has to be exposed to oxygen for oxidation to occur.
I think what you are reffering to is iron oxide which is commonly known as rust
The iron will become oxidized and we will say that it has become rusty.
Oxygen gas is evolved when chlorine is passed into water and subsequently exposed to sunlight, which causes the chlorine to react with water, releasing oxygen and forming hypochlorous acid.
Water that has been exposed oxygen typically contains 2-3 millimole of oxygen.
Water is a compound containing two elements: oxygen and hydrogen, H2O.
