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 w... More »

Adding salts, oxidizers and acids to the water speeds up the process, causing rust to appear faster on the surface of the metal, according to the Seattle Post-Intelligencer. Rust occurs in the presence of iron, water and... More »

Elevated temperature, immersion in a humid and oxygen rich environment, contact with a metal that is lower in the electrochemical series, and mechanical agitation are conditions that cause an iron nail to rust faster. Ru... More »

There are several different ways to create oxygen, but the easiest is by passing an electric current through water to separate the hydrogen atoms from the oxygen atoms. This process is called electrolysis, and is one of ... More »

Water is formed when oxygen and hydrogen atoms combine, and it takes a total of three atoms to make a water molecule. Two of the atoms are hydrogen and the last atom is oxygen, hence the chemical formula H2O. More »

Fe2O3, or rust, is iron oxide formed by a redox reaction of iron and oxygen in the presence of water. Iron is the reducing agent, as it gives up electrons, while oxygen is the oxidizing agent gaining electrons. Simply ex... More »

Oxidation is the reaction that occurs by adding oxygen to other materials, often in combination with water. Oxidation is commonly called rust, but this term technically only applies to iron. Oxidation can occur in a vari... More »
