What is Na2O? Important knowledge about Na2O.

Definition of Na₂O
Na₂O, commonly known as Sodium Oxide in English, is a chemical compound. It consists of 2 sodium atoms (Na) and 1 oxygen atom (O). Na₂O has an atomic mass of 62, including 46 atomic mass units from sodium and 16 from oxygen. With this molecular structure, Na₂O has an ionic structure of 2Na+ and O₂-.

Properties of Na₂O
2.1 Physical properties of Na₂O
Na₂O is in a solid state, white in color and odorless. This is a base, so it has a high pH level.
2.2 Chemical properties of Na₂O
Na₂O reacts with water to form sodium hydroxide (NaOH) and generates a large amount of heat.

Common chemical equations
Na₂O reacts with acids (HCl, H₂SO₄,…) to form salts and water.
Example: Na₂O + H₂SO₄ -> Na₂SO₄ + H₂O
With non-metals, Na₂O can react with CO₂ to form Na₂CO₃.

Preparation of Na₂O
4.1 Laboratory preparation
Na₂O can be prepared by heating sodium with oxygen.
4.2 Industrial preparation
In industry, Na₂O is usually produced by burning sodium in the air.
