Manganese carbonate is a compound with the chemical formula Mn CO 3. Manganese carbonate occurs naturally as the mineral rhodochrosite but it is typically produced industrially. It is a pale pink, water-insoluble solid. Approximately 20,000 metric tonnes were produced in 2005. [3]
Rhodochrosite is a manganese carbonate mineral with chemical composition MnCO 3. In its pure form (rare), it is typically a rose-red colour, [ 5 ] but it can also be shades of pink to pale brown. It streaks white, [ 6 ] and its Mohs hardness varies between 3.5 and 4.5.
A particularly common oxidation state for manganese in aqueous solution is +2, which has a pale pink color. Many manganese(II) compounds are known, such as the aquo complexes derived from manganese(II) sulfate (MnSO 4) and manganese(II) chloride (MnCl 2). This oxidation state is also seen in the mineral rhodochrosite (manganese(II) carbonate ...
Manganese(II) acetate are chemical compounds with the formula Mn(CH 3 CO 2) 2 ·(H 2 O)n where n = 0, 2, 4. These materials are white or pale pink solids. Some of these compounds are used as a catalyst and as fertilizer. [3]
