Question

List the conditions that help in the rusting of iron write down the chemical reaction involved

Answer 1

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.

Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur.

Answer 2

Answer:

Rusting of iron takes place in the presence of moisture and air. So the presence of air and water vapour in air are two necessary conditions for rusting of iron.
