Why Metal Rusts at Jai Denison blog

Why Metal Rusts. The most commonly used metal that contains iron is steel. An electrochemical process involving an anode (a piece of metal that readily gives up electrons), an electrolyte (a liquid that helps electrons move) and a cathode (a piece of metal that readily accepts electrons). Wrought iron has a higher carbon content than pure iron, and with more carbon, it’s naturally better protected against rusting. Iron (or steel) rusting is an example of corrosion: Rust occurs when iron or its alloys, such as steel, corrode. Iron rusts due to oxygen converting iron into iron oxide. For starters, only metal that contains iron will rust. Given enough time, any piece of iron will change entirely into rust and disintegrate. With that said, pure iron, wrought iron and cast iron can all rust when exposed to moisture or air. The familiar red form of rust is (fe 2 o 3), but iron has other oxidation states, so it can form other colors of rust. Iron rusting is a chemical change because it involves a reaction between iron, oxygen, and water creating a new substance, iron oxide. Rusting occurs when iron or its alloys are exposed to moist air. Let’s take a look at the science behind this common occurrence. The oxygen and water in air react with the metal to form the hydrated oxide. Metals that don’t contain iron, like aluminum and titanium, will not rust (although they will oxidize).

The surface of a piece of iron will corrode first in the presence of oxygen and water.
