What is BaO? Important knowledge about BaO

1. Definition of BaO:

BaO, also known as Barium Oxide in English, is a chemical compound with a molar mass of 153.3265 g/mol. The atomic mass of BaO is mainly due to the two atoms, Barium (Ba) and Oxygen (O), that constitute it. The BaO molecule consists of a Barium ion (Ba₂+) and an Oxygen ion (O₂-), forming a BaO ionic molecule.

2. Properties of BaO:

2.1 Physical properties of BaO:

BaO is a solid at room temperature. This substance is white to gray in color and has no distinctive odor. BaO has a neutral pH.

2.2 Chemical properties of BaO:

BaO is an alkaline chemical, capable of reacting with acids to form salts and water. BaO can also react with water to form barium hydroxide.

3. Common reaction equations of BaO:

• BaO + H₂SO₄ -> BaSO₄ + H₂O
• BaO + 2HCl -> BaCl₂ + H₂O
• BaO + H₂O -> Ba(OH)₂
• BaO + CO₂ -> BaCO₃
• BaO + SiO₂ -> BaSiO₃

4. Synthesis of BaO:

4.1 Synthesis of BaO in the laboratory:

• Ba + 1/2O₂ -> BaO
• Ba(OH)₂ + 2NH₃ -> BaO + 2NH₄OH

4.2 Industrial method of BaO synthesis:

BaO is typically produced by heating barium carbonate at high temperatures.
