Question

explain the term 'corrosion' with an example write a chemical equation to show the process of corrosion of iron

Answer 1

Corrosion is a natural process, which converts a refined metal to a more chemically-stable form, such as its oxide, hydroxide, or sulfide. It is the gradual destruction of materials by chemical and/or electrochemical reaction with their environment.

4Fe + 3O2 + 10H2O → 2Fe.2O3.10H2O
