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]
Kutnohorite is a rare calcium manganese carbonate mineral with magnesium and iron that is a member of the dolomite group. It forms a series with dolomite, and with ankerite.The end member formula is CaMn 2+ (CO 3) 2, [6] but Mg 2+ and Fe 2+ commonly substitute for Mn 2+, with the manganese content varying from 38% to 84%, [2] so the formula Ca(Mn 2+,Mg,Fe 2+)(CO 3) 2 better represents the species.
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.
Manganocalcite. Manganoan calcite or manganocalcite is a variety of calcite rich in manganese, which gives the mineral a pink color. [1] Its chemical formula is (Ca,Mn)CO 3.It was first reported from the Banská Štiavnica Mining District, Slovak Republic, [1] but is widely distributed around the world, notably in the Cave of Swords at Naica, Chihuahua, Mexico as well as in Bulgaria.
Ankerite is a calcium, iron, magnesium, manganese carbonate mineral of the group of rhombohedral carbonates with the chemical formula Ca(Fe,Mg,Mn)(CO 3) 2.In composition it is closely related to dolomite, but differs from this in having magnesium replaced by varying amounts of iron(II) and manganese.
The sodium carbonate test (not to be confused with sodium carbonate extract test) is used to distinguish between some common metal ions, which are precipitated as their respective carbonates. The test can distinguish between copper (Cu), iron (Fe), and calcium (Ca), zinc (Zn) or lead (Pb). Sodium carbonate solution is added to the salt of the ...

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
