  2. Manganese(II) carbonate - Wikipedia

    en.wikipedia.org/wiki/Manganese(II)_carbonate

    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]

  3. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    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.

  4. Rhodochrosite - Wikipedia

    en.wikipedia.org/wiki/Rhodochrosite

    Rhodochrosite forms a complete solid solution series with iron carbonate . Calcium (as well as magnesium and zinc, to a limited extent) frequently substitutes for manganese in the structure, leading to lighter shades of red and pink, depending on the degree of substitution. This is the reason for the rose color of rhodochrosite.

  5. Manganese (II) acetate - Wikipedia

    en.wikipedia.org/wiki/Manganese(II)_acetate

    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. These materials are white or pale pink solids.

  6. Manganese(III) acetate - Wikipedia

    en.wikipedia.org/wiki/Manganese(III)_acetate

    Although manganese(III) triacetate has not been reported, salts of basic manganese(III) acetate are well characterized. Basic manganese acetate adopts the structure reminiscent of those of basic chromium acetate and basic iron acetate. The formula is [Mn 3 O(O 2 CCH 3) 6 L n]X where L is a ligand and X is an anion.

  7. Manganese dioxide - Wikipedia

    en.wikipedia.org/wiki/Manganese_dioxide

    4 and leaving a residue of purified manganese dioxide. [8] These two steps can be summarized as: MnO 2 + N 2 O 4 ⇌ Mn(NO 3) 2. In another process, manganese dioxide is carbothermically reduced to manganese(II) oxide which is dissolved in sulfuric acid. The filtered solution is treated with ammonium carbonate to precipitate MnCO 3.

  8. Manganese lactate - Wikipedia

    en.wikipedia.org/wiki/Manganese_lactate

    Manganese lactate forms light pink crystals. Manganese lactate is soluble in water and ethanol. Manganese lactate forms crystalline hydrates of composition Mn(C 3 H 5 O 3) 2 •n H 2 O, where n = 2 and 3. [3] Each lactate is a bidentate ligand. Two water molecules coordinate directly to the metal as well, cis to each other, to complete the ...

  9. Carbonate - Wikipedia

    en.wikipedia.org/wiki/Carbonate

    A carbonate is a salt of carbonic acid, (H 2 CO 3), [2] characterized by the presence of the carbonate ion, a polyatomic ion with the formula CO 2− 3. The word "carbonate" may also refer to a carbonate ester , an organic compound containing the carbonate group O=C(−O−) 2 .
