What is BaI2? Important knowledge about BaI2

1. Definition of BaI₂

BaI₂, also known as Barium Iodide in English, is a colorless crystalline chemical substance. BaI₂ is composed of one Barium atom (Ba) and two Iodine atoms (I). The atomic mass of BaI₂ is 391.136 g/mol. In its molecular structure, the Barium atom forms ionic bonds with two Iodine atoms to form a crystalline solid.

2. Properties of BaI₂

2.1 Physical properties: BaI₂ is a colorless, odorless crystalline solid with a neutral pH.

2.2 Chemical properties: BaI₂ has the ability to react with strong oxidizing agents to form Iodine and Barium.

3. Common chemical equations

BaI₂ can react with some metals, acids, non-metals, and salts to produce different products. For example, BaI₂ can react with sulfuric acid (H₂SO₄) to produce barium sulfate (BaSO₄) and hydrogen iodide (HI).

4. Synthesis of BaI₂

4.1 Laboratory synthesis: BaI₂ is typically synthesized by reacting Barium with Iodine.

4.2 Industrial synthesis: In industry, BaI₂ is usually produced by reacting Barium Carbonate (BaCO₃) with Hydrogen Iodide (HI) to produce BaI₂ and CO₂ gas.
