This is a normal rusting.
The cause of iron rust is oxygen and water.
The gas that makes a wet iron nail rust is oxygen. When iron comes into contact with oxygen in the presence of water, it undergoes a chemical reaction called oxidation, forming iron oxide, which is the rust that we see.
Salt water.
Any water makes iron rust. Rust is iron oxide. It happens when water allows the oxygen to dissolve in it and get to the surface of the metal. Salt water has dissolve salts in it which makes it work faster.
I'm not so good at science but I think The Oxygen from the water (H20) oxidises the iron and makes iron oxide, which is rust.
The gas that forms rust with water and iron is oxygen. Rust is formed when iron reacts with oxygen and water in a process called oxidation.
Nails do not rust in water. Nails only rust in water if oxygen is present. This is because the iron in nails react with oxygen and water to form a compound called hydrated iron(III) oxide.
iron combines with oxygen in the presence of water in a process called oxidation. the product of oxidation is rust. rock that contains iron also oxidizes, or rust. rust makes rock soft and crumbly and gives it a red or brown color.

Iron combines with oxygen in the air to form ferric oxide, also known as rust.
The reddish brown flaky substance formed on iron is called rust. Rust is caused by the oxidation of iron in the presence of water and oxygen.
An iron nail will rust slowly in distilled water when that water has dissolved oxygen. If you get rid of the oxygen by boiling and keep it from getting back in then the iron nail will not rust at all.
