The chemical formula for iron (II) carbonate is FeCO3. This compound is an iron salt of carbonic acid and is also called ferrous carbonate, ferrous monocarbonate and Blaud's mass.
Iron (II) carbonate forms during chemical reactions between iron (II) salts and alkali carbonate salts and precipitates in the form of a white solid that has no particular odor. This compound is soluble in water and carbonic acid solutions and changes color when exposed to air. When heated at approximately 392 degrees Fahrenheit, this salt starts to decompose.
Iron (II) carbonate is used therapeutically as a nutritional supplement for adults and infants. This chemical is also one of the FDA-approved iron salts that can be added to animal feeds.
