Question

what is corrosion ? what reaction take place in corrosion of iron ? why aluminium sheets do not corrode?​

Answer 1

Answer:

Corrosion, wearing away due to chemical reactions, mainly oxidation (see oxidation-reduction, oxide). It occurs whenever a gas or liquid chemically attacks an exposed surface, often a metal, and is accelerated by warm temperatures and by acids and salts.

Corrosion Reaction equation

Fe → Fe2+ + 2e–

The oxidation state of iron is further increased by the oxygen atom when water is present. Now, the following acid-base reactions occur between the iron cations and the water molecules.

Explanation:

Aluminum oxide consists of atoms of aluminum and oxygen bonded together. ... structure changes just enough to become chemically inert and thus unable to react rapidly with additional water molecules or atmospheric oxygen. This change in molecular structure is why aluminum oxide metal resists corrosion. wlcm and thnku suhani

Answer 2

Answer:

Corrosion is related to rusting. It is the gradual destruction of materials by chemical and/or electrochemical reaction with their environment. It is a irreversible damage of metal or other things.
