KobolttiIIkarbonaatti

Koboltti(II)karbonaatti is an inorganic chemical compound with the formula CoCO3. It is a salt formed from cobalt(II) ions and carbonate ions. In its pure form, it appears as a pink crystalline solid.

This compound is found naturally as the mineral spherocobaltite. It is relatively insoluble in water but dissolves in acids, producing carbon dioxide gas. When heated, koboltti(II)karbonaatti decomposes to form cobalt(II) oxide and carbon dioxide.

Koboltti(II)karbonaatti can be synthesized by reacting a soluble cobalt(II) salt, such as cobalt(II) chloride or cobalt(II) sulfate, with a soluble carbonate, like sodium carbonate, in an aqueous solution. The reaction typically results in the precipitation of koboltti(II)karbonaatti.

Historically and in modern applications, koboltti(II)karbonaatti has served as a source of cobalt. It can be used in the production of other cobalt compounds and pigments. Its pink color has also led to its use as a colorant in ceramics and glass. Due to the toxicity associated with cobalt compounds, handling and disposal of koboltti(II)karbonaatti require appropriate safety measures.
