Question

What is corrosion? Write the reaction rusting of iron?​

Answer 1

Answer:

The causes of corrosion require the presence of water and oxygen. Water can combine with carbon dioxide in the air to form carbonic acid, a weak acid. When this acidic solution reaches iron, two reactions occur. ... Free oxygen reacts with dissolved iron to form iron oxide, and iron oxide is rust.

Answer 2

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

4Fe + 3O2 + 6H2O → 4Fe(OH)3
