What is FeCO3? Important knowledge about FeCO3.

Definition of FeCO₃
FeCO₃, also known as Siderite, is a chemical compound of iron (Fe), carbon (C), and oxygen (O). In English, it is often referred to as Iron(II) carbonate. The molecular weight of FeCO₃ is 115.86 g/mol. This molecule is composed of one iron(II) ion (Fe₂+) and one carbonate ion (CO₃ 2-).

Properties of FeCO₃
2.1 Physical properties of FeCO₃: Siderite is solid at room temperature, its color varies from light yellow to brown-black. It does not have a distinctive smell and has a neutral pH level.
2.2 Chemical properties of FeCO₃: FeCO₃ is insoluble in water but dissolves easily in strong acids such as hydrochloric acid, producing carbon dioxide (CO₂) and iron(II) ions.

Common chemical equations with FeCO₃
FeCO₃ does not react with metals, non-metals, and salts. However, it can react with acids, for example:

• FeCO₃ + 2HCl -> FeCl₂ + CO₂ + H₂O
• FeCO₃ + 2HNO₃ -> Fe(NO₃)₂ + CO₂ + H₂O
• FeCO₃ + H₂SO₄ -> FeSO₄ + CO₂ + H₂O

Synthesis of FeCO₃
4.1 Laboratory synthesis of FeCO₃: FeCO₃ can be synthesized through the reaction between iron(II) ions and carbonate ions.

• Fe₂+ + CO₃ 2- -> FeCO₃

4.2 Industrial synthesis of FeCO₃: In industry, FeCO₃ is typically produced from the reaction between iron and carbon dioxide at high pressure and low temperature.
