how is rust a chemical change

Best answer


Theoxygen and water in air react with the metal to form the hydrated oxide. The familiar red form of rust is (Fe2O3),but iron has other oxidation states,so it can form other colors of rust. The Chemical Reaction That Forms Rust

  • Is rust a physical or chemical change?

  • Rust is essentially iron oxide or sometimes iron alloys. Rusting of iron is a chemical change rust is formed when iron (or an alloy of iron) is exposed to oxygen in the presence of moisture. This phenomenon is a chemical change as iron combines with oxygen in presence of water to form a new compound, iron oxide.

  • What are the reactants of rusting?

  • Rusting, a well known example of corrosion, is the breakdown of the metal iron. The reactants of this chemical reaction are iron, water, and oxygen, and the product is hydrated iron oxide, better known as rust.

  • Is rust an oxidization reaction?

  • Although rust is considered the result of an oxidation reaction, it’s worth noting not all iron oxides are rust. Rust forms when oxygen reacts with iron, but simply putting iron and oxygen together isn’t sufficient.

  • How is Rust formed?

  • The Chemical Reaction That Forms Rust Although rust is considered the result of an oxidation reaction, it’s worth noting not all iron oxides are rust. Rust forms when oxygen reacts with iron, but simply putting iron and oxygen together isn’t sufficient. Although about 21% of air consists of oxygen, 1 锘?rusting doesn’t occur in dry air.
