Q:

What is the cause of iron rust?

A:

Quick Answer

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.

Full Answer

The chemical component of rust is iron oxide. Its chemical formula is Fe2O3. Rust is nothing more than simply corroded iron. Because of this reaction, the iron is being dissolved by an electrolyte called carbonic acid. The oxygen that is released by the water combines with the dissolved iron. The combination of those two is called rust. Iron and steel rust more easily than aluminium.

  • Q:

    How does rust form?

    A:

    Rust forms on iron due to an oxidation reaction that occurs when it comes into contact with oxygen and water. The reaction of iron, oxygen and water forms hydrated iron(III) oxide, which is known as rust. Acid rain or saltwater can cause iron to rust more quickly.

    Does chrome rust?

    A:

    Chrome does rust, because it is a metal that readily interacts with moisture and oxygen. Chrome is formed by electroplating a metal with the element chromium, which has greater corrosion resistance than most other metals and increases the durability of the surface.

  • Q:

    What is the chemical equation for the rusting of iron?

    A:

    The oxidation reaction of iron and oxygen to form the substance that is commonly called rust occurs according to this equation: 4Fe + 3O2 = 2Fe2O3. Water is also required for this reaction to occur, but because the total amount of water does not change, it is not included in the equation.
