Iron has to be exposed to oxygen for oxidation to occur.
Iron rust (iron oxide) is formed when iron is exposed to moist air due to the process of oxidation.
what must be present for oxidation-reduction to occur?
The iron will become oxidized and we will say that it has become rusty.
Iron or steel will rust, this is called oxidation. It's a reaction between oxygen and iron or steel
Rusting of iron occurs when iron is exposed to oxygen and water, which leads to the formation of iron oxide (rust) on the surface of the iron. The presence of both oxygen and water is necessary for the rusting process to occur. Rusting can be accelerated by factors such as saltwater, acids, and pollutants in the atmosphere.

Iron rust (iron oxide) is formed when iron is exposed to moist air due to the process of oxidation.
If exposed to the elements, minutes.
For rusting to occur, iron must be exposed to oxygen and moisture in the air. This triggers a chemical reaction known as oxidation, which causes the iron to form iron oxide, or rust. Presence of an electrolyte such as salt can accelerate the rusting process.
Iron nails exposed to vinegar for 2 days will undergo a chemical reaction called oxidation, resulting in the formation of iron oxide (rust) on the surface of the nails. This reaction occurs due to the acidity of the vinegar, which speeds up the oxidation process of the iron.

Iron-containing rocks such as iron-rich sandstones, shales, and magnetite will undergo oxidation when exposed to air and water, leading to the formation of iron oxide minerals like hematite or limonite. These rocks may develop a reddish or yellowish color as a result of the oxidation process.
Yes, hematite is an iron oxide mineral that forms when iron-containing minerals are exposed to oxygen and undergo oxidation. This process causes the iron to combine with oxygen and form hematite, which is a common mineral found in a variety of geological settings.
When fruit flesh is exposed to air, it experiences oxidation, much like iron does. This reaction doesn't result in the rust that iron's reaction does, but it is responsible for the brown coloring that this exposed fruit flesh takes on.
No, oxygen does not directly affect nail rusting because rusting specifically refers to the oxidation of iron metal. Nails are made of iron, and they rust when exposed to oxygen and water. Oxygen in the air reacts with the iron in the nail to form iron oxide, or rust.
