Explain:
(a) Rusting in from
(b) Corrosion in copper and silver
Write the chemical reactions and name the products formed.
Answers
Answer:
(a) Rust is an iron oxide, a usually reddish brown oxide formed by the reaction of iron and oxygen in the presence of water or air moisture. ... Rusting is the common term for corrosion of iron and its alloys, such as steel. Many other metals undergo similar corrosion, but the resulting oxides are not commonly called rust.
(b) Corrosion is usually defined as the degradation of metals due to an electrochemical process. The formation of rust on iron, tarnish on silver, and the blue-green patina that develops on copper are all examples of corrosion. ... The oxidation-reduction reactions of copper metal in the environment occur in several steps.
Answer:
(a) Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Here is the word equation for the reaction: iron + water + oxygen → hydrated iron(III) oxide.
(b) I don't know .sorry
