Calcium carbonate - Essential Chemical Industry
Calcium carbonate (limestone) is heated to form calcium oxide (quicklime) and carbon dioxide: It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed atmospheric pressure and the decomposition proceeds to completion.

Do It Yourself | Causes of Color - WebExhibits
You can test sodium carbonate and calcium carbonate to prove to yourself that it is the metallic part (the ion) of the compound producing the color. Hence, sodium carbonate will produce a yellow flame and calcium carbonate (chalk or limestone) will produce a red-orange flame.
Calcium carbonate | CaCO3 - PubChem
Calcium Carbonate is the carbonic salt of calcium (CaCO3). Calcium carbonate is used therapeutically as a phosphate buffer in hemodialysis, as an antacid in gastric hyperacidity for temporary relief of indigestion and heartburn, and as a calcium supplement for preventing and treating osteoporosis.
Corrosionpedia - What is Carbonate Alkalinity? - …
2018/7/3· Alkalinity is usually measured in milligrams per liter of calcium carbonate, which is a calcium ion bound to a carbonate ion. Carbonate alkalinity is especially important in environmental contexts. When a water''s pH is above 8.3, its alkalinity tends to come from carbonate ions, and below that threshold the alkalinity usually comes from bicarbonate ions.
Synthesis and Characterisation of Calcium Carbonate …
TEM was also used to study the calcium carbonate crystal particles. The images of the crystal presented in both Figures 2(a) and 2(b) reveal a rod shape of calcium carbonate aragonite polymorphs. The particles in Figure 2(a) are uniformly distributed at the nanometre scale and were formed in the microemulsion system; this system is considered an ideal medium for the preparation of inorganic
