Rusting is the process in which iron turns into iron oxide. It happens when iron comes into contact with water and oxygen. The process is a type of corrosion that occurs easily under natural conditions.
Chemical names for rust include iron oxide, ferric oxide and hematite. The substance is also known by its chemical formula, Fe2O3, which represents the two elements--iron and oxygen--that compose rust.
The scientific name for rust is iron oxide, and its chemical formula is Fe2O3. The scientific name for rust as a verb, the process of rusting, is oxidation.
Rusting is a chemical reaction where iron is slowly broken down when exposed to water and air. It is categorized as an oxidation reaction; oxygen, water and iron react to form hydrated iron (III) oxide, which is known as rust. Rusting is a good example of metal corrosion.
Some solutions to clean rust include mixing salt with lime or using baking soda with water. Another solution uses white vinegar and aluminum foil. It is best for individuals to apply these solutions with a soft brush, such as a toothbrush, instead of something abrasive, like steel wool.
Not all metal rusts, but the metals that do rust do so because of an oxidation reaction between the metal and water and oxygen. Oxidation is the process by which a substance incorporates oxygen into its molecular structure.
The formation of rust represents a chemical change. When a chemical change occurs, the substance or substances present at the beginning are no longer present at the end of the change. Once a chemical change occurs, it theoretically cannot be undone.
A rust killer, or converter, chemically converts the rust from iron oxide to iron tannate, which does not corrode the metal of a vehicle. A good rust converter for cars is Corroseal, which can be purchased at hardware stores by the gallon.
Rust is caused when iron comes into direct contact with water and oxygen. Technically, rust comes from a chemical reaction between carbon dioxide from the air, water and the iron. Rusting is an oxidation reaction.
Rust on metal is caused by surface metal atoms and molecules forming metal oxides in the presence of oxygen and water. Iron is the most common material that rusts, forming iron oxides, but most other metals can rust as well.
