What is the Chemical Compound FeCO3?

The chemical compound FeCO₃ is known as Iron(II) Carbonate. It is a compound consisting of iron in its +2 oxidation state and carbonate ions (CO₃^2-).

Iron(II) Carbonate is commonly found in nature as the mineral siderite. Siderite is an important ore of iron and is often used in the production of iron and steel. The compound is typically a pale yellow or brownish color and can be found in sedimentary rocks.

In terms of its chemical properties, FeCO₃ is relatively stable but can decompose when heated, releasing carbon dioxide (CO₂) and forming iron(II) oxide (FeO). This decomposition reaction is often used in industrial processes to produce iron oxides.

Overall, FeCO₃ plays a significant role in both natural geological processes and industrial applications.
