Question

on what factors corrosion of iron depend? write the chemical composition of rust​

Answer 1

Rusting of iron refers to the formation of rust, a mixture of iron oxides, on the surface of iron objects or structures. This rust is formed from a redox reaction between oxygen and iron in an environment containing water (such as air containing high levels of moisture). The rusting of iron is characterized by the formation of a layer of a red, flaky substance that easily crumbles into a powder.

The chemical formula for rust is Fe2O3, which is called iron oxide but is also known as ferric oxide.
