Rust - Wikipedia, the free encyclopedia
Rust is a general term for a series of iron oxides, usually red oxides, formed by the reaction of iron and oxygen in the presence of water or air moisture. Several forms of rust are distinguishable v...

Water alone does not cause steel to rust, ... Rust is scientifically called oxidation, which occurs when oxygen comes in long-term contact with certain metals. Over time, the oxygen combines with the metal at an atomic level, forming a new compound called an oxide and weakening the bonds of the metal itself.

We often used the words oxidation and rust interchangeably, but not all materials which interact with oxygen molecules actually disintegrate ... Metals don't contain free radicals. Free radicals are involved in some oxidation processes, but the main reason some metals oxidize in air and others don't is that for many metals,

As Ted stated only ferrous metals (those which contain iron) can rust. But nearly everything oxidizes... striking a match causes rapid oxidation of the chemicals in the match head. ... Footnote: Pure water will not cause oxidation (by transfer of electrons-the chemical process) because PURE water will not conduct electricity.

Rust is a byproduct of the reaction (oxidation) that occurs when iron-ferrous metal (metal with iron in it) is exposed to oxygen. This article uses the term 'metal' to mean iron-ferrous metal, steel or steel alloy (steel with other metals mixed in). ... Media can cause intense heat from impacting surface,

Rust is a generic term to describe a family of different oxides, Fe(OH)2, Fe(OH)3, FeO(OH), Fe2O3.H2O that forms when iron corrodes. ... The corrosion of metals is an electrochemical process. That is, ... Oxidation reactions (corrosion) occur at the surface of the anode and reduction reactions occur at the surface of the cathode...

Rusting of metals is a special case of metal oxidation. Iron will oxidize to form rust. Water will cause metals to rust; this reaction can be accelerated by adding salts. In the corrosion process, metals get oxidized.

Oxidation takes place when oxygen reacts with earth materials. Oxygen dissolved in water combines with atoms of metallic elements abundant in silicate minerals. Attacking metals in the soil, oxidation causes them to rust leaving the soil a brownish red to red color.

In this section, you'll learn a lot more about rust and how it occurs. And you'll attempt to find out which metals rust the fastest, by exposing them to water and to salt water ... When you've finished, you'll have a better understanding of corrosion, the process of oxidation, and the properties of different metals.
