The carbonate is insoluble in water but, like most carbonates, hydrolyses upon treatment with acids to give water-soluble salts. Manganese carbonate decomposes with release of carbon dioxide at 200 °C to give manganese (II) oxide: MnCO 3 → MnO + CO 2. This method is sometimes employed in the production of manganese dioxide for dry-cell ...
