Difference Between Calcium and Calcium .Deze pagina vertalen

25-11-2015 · Key Difference – Calcium vs. Calcium Carbonate The key difference between Calcium and Calcium Carbonate is that Calcium (Ca) is a pure chemical element and Calcium carbonate (CaCO 3) is Calcium containing compound; it is one of the most abundant natural forms of Calcium found in nature.Calcium is an essential mineral for the human body, and it has so many functions.

Formula and structure: The chemical formula of calcium carbonate is CaCO 3 and its molar mass is 100.1 g/mol. It is a salt made of the bivalent calcium cation (Ca 2+) and the bidentate carbonate anion (CO 3 2-), in which the carbon is attached to two oxygen atoms through single bonds and one oxygen atom through a double bond.. Occurrence: Calcium carbonate occurs naturally in several mineral ...

Calcium carbonate has a very low solubility in pure water (15 mg/L at 25°C), but in rainwater saturated with carbon dioxide, its solubility increases due to the formation of more soluble calcium bicarbonate. Calcium carbonate is unusual in that its solubility increases as the temperature of the water decreases.
