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.
What else can I help you with?
Does iron reacts with water?
Pure Iron (Fe) doesn't directly react with water, but it will oxidize (rust), especially if the iron is just wet and is exposed to air a lot. I believe iron will eventually oxidize if kept completely underwater too, but as there is less free Oxygen for it to react with down there, it is a longer process.
What does iron have to be exposed to for oxidation to occur?
Iron has to be exposed to oxygen for oxidation to occur.
What chemical will turn reddish when exposed to water and oxygen?
I think what you are reffering to is iron oxide which is commonly known as rust
Why should you dry an iron skillet immediately after washing?
Iron left damp and exposed to oxygen is prone to rust as the iron, water and air react to oxidize iron at the surface of the pan. Drying an iron skillet immediately after washing helps to protect the skillet from rusting.
Why do metals often lose their shine and appear dull?
Most metals lose their luster when they are exposed to water because they react with the oxygen in the water and oxidize. An example is iron that reacts with the water to produce iron oxide, or rust.
Does copper oxidize when exposed to water?
Yes, copper can oxidize when exposed to water, forming a greenish layer called copper oxide.
Will potato oxidize?
Yes, when a potato is exposed to air, it can oxidize. This oxidation process causes the potato to turn brown due to the production of enzymes that react with oxygen in the air. To prevent this, store cut potatoes in water or acidic solutions.
What causes nails to oxidize?
water (or water vapour) and oxygen salt speeds the process up
What happens to a penny in the ocean?
It will sink. And it will slowly oxidize from the dissolved oxygen in the water.

What 2 compounds are in mineral water?
hygrogen and oxygen

What gas is evolved when chlorine is passed into water and subsequently exposed to sunlight?
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.
How does oxygen level vary in different forms of running water?
Water that has been exposed oxygen typically contains 2-3 millimole of oxygen.
Why should you dry an iron skillet immediately after washing?
Iron left damp and exposed to oxygen is prone to rust as the iron, water and air react to oxidize iron at the surface of the pan. Drying an iron skillet immediately after washing helps to protect the skillet from rusting.
What chemical is rust?
Iron and water exposed to oxygen Ferrous oxide
