Cobalt(II) Carbonate
Cobalt(II) carbonate is the inorganic compound with the formula CoCO3. This reddish paramagnetic solid is an intermediate in the hydrometallurgy, hydrometallurgical purification of cobalt from its ores. It is an inorganic pigment, and a precursor to catalysts. Cobalt(II) carbonate also occurs as the rare red/pink mineral spherocobaltite. Preparation and structure It is prepared by combining solutions cobaltous sulfate and sodium bicarbonate: :CoSO4 + 2 NaHCO3 → CoCO3 + Na2SO4 + H2O + CO2 This reaction is used in the precipitation of cobalt from an extract of its roasted ores. CoCO3 adopts a structure like calcite, consisting of cobalt in an octahedral coordination geometry. Reactions Like most transition metal carbonates, cobalt carbonate is insoluble in water, but is readily attacked by mineral acids: :CoCO3 + 2 HCl + 5 H2O → [Co(H2O)6]Cl2 + CO2 It is used to prepare many coordination complexes. The reaction of cobalt(II) carbonate and acetylacetone in ...
