Iron(II) carbonate

0Iron(II) carbonate is an inorganic compound with the chemical formula FeCO3. It is a greenish-white solid which is stable under normal atmospheric conditions, but decomposes when heated. Iron(II) carbonate is not readily available commercially, but can be prepared in the laboratory.

Chemical Properties

Iron(II) carbonate is a salt of carbonic acid and iron. It is insoluble in water but dissolves in acids to form carbon dioxide and the corresponding iron salt. When heated, it decomposes to form iron(II) oxide and carbon dioxide.

Preparation

Iron(II) carbonate can be prepared in the laboratory by reacting a solution of iron(II) sulfate with sodium carbonate. The iron(II) carbonate precipitates out of solution and can be collected by filtration.

Uses

Iron(II) carbonate is used in the steel industry as a source of iron. It is also used in the preparation of other iron compounds.

Safety

Iron(II) carbonate is not considered to be particularly hazardous, but it can be harmful if ingested or inhaled in large quantities. It should be handled with care and stored in a cool, dry place.
