What is Fe? Important knowledge about Fe.

1. Definition of Fe:

1.1 The common name of Fe is iron. Its English name is also Iron.

1.2 The atomic mass of iron is 56.

1.3 The atomic weight of iron is also 56.

1.4 The ionic structure of iron is usually Fe₂+ or Fe₃+.

2. Properties of Fe:

2.1 Physical properties of Fe: Iron is solid at room temperature, its color ranges from bright silver to grayish-green, and it has no smell. The pH of iron is not defined because it is a solid.

2.2 Chemical properties of Fe: Iron can react with oxygen and water to form iron oxide. It can also react with acid.

3. Common chemical equations for Fe:

Some examples of iron reactions:

3.1 Metal: Fe + CuSO₄ -> FeSO₄ + Cu

3.2 Acid: Fe + 2HCl -> FeCl₂ + H₂

3.3 Non-metal: 2Fe + O₂ -> 2FeO

3.4 Salt: Fe + CuCl₂ -> FeCl₂ + Cu

4. Preparation of Fe:

4.1 Laboratory preparation of Fe:

For example, iron can be prepared by heating iron ore (Fe₂O₃) in the presence of charcoal.

4.2 Industrial preparation of Fe:

In industry, iron is produced from iron ore using a high-temperature furnace (blast furnace) in a process called the Bessemer process.
