Manganese Carbonate CAS#598-62-9
Natural Source: Manganese(II) carbonate is derived from the mineral rhodochrosite, ensuring a natural origin.
Laboratory Preparation: Easily synthesized by adding sodium bicarbonate to manganese(II) salt saturated with carbon dioxide.
Monohydrate Form: The product is in a stable monohydrate form (MnCO3•H2O), ideal for various applications.
Pale Pink Appearance: It forms a visually distinct pale pink precipitate, useful in both industrial and laboratory settings.
Manganese(II) carbonate is extracted from the naturally occurring mineral rhodochrosite. In the laboratory, it can be prepared as a pale pink precipitate by adding sodium bicarbonate to a manganese(II) salt solution that is saturated with carbon dioxide. The resulting product is the monohydrate form, MnCO3•H2O.

Manganese Carbonate is widely used as an additive in plant fertilizers to address manganese deficiencies in crops. It also finds applications in health foods, ceramics (as a glaze colorant and flux), and concrete stains. Additionally, it is employed in medicine as a hematinic, a nutrient essential for blood cell formation during hematopoiesis, with key hematinics including iron, B12, and folate.
