Question

what is meant by the rusting of iron? state two conditions necessary for the rusting of iron to occure. explain how. rusting damages iron objects.​

Answer 1

Explanation:

The rusting of iron (iron in contact with water forms the anode and in contact with air forms the cathode. At the anode, iron is oxidized to Fe2+, and at the cathode, oxygen is reduced to water. Iron and steel rust when they come into contact with water and oxygen. Both water and oxygen are needed for rusting to occur

Answer 2

Explanation:

Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust.

2 conditions necessary for rusting of iron are as follows:-

I. Presence of atmospheric oxygen or air

II. Presence of moisture in air

When iron comes in contact with water and oxygen it reacts with them and the products are rust (ferric oxide) and water . The rust gradually falls off exposing fresh metal to further rust causing weakness in the iron . This is how it causes damage to iron objects.
