Calcium carbonate - Essential Chemical Industry

Deze pagina vertalen

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.

Thermal decomposition of calcium carbonate | .

Deze pagina vertalen

Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate.

Calciumcarbonaat - Wikipedia

Zie ook de artikelen over kalksteen en de mineralen calciet en aragoniet.: Calciumcarbonaat komt in de natuur veel voor als het mineraal calciet.Het sedimentair gesteente kalksteen en de metamorfe vorm hiervan, marmer, zijn grotendeels uit calciet opgebouwd.In de natuur is calciet meestal gedeeltelijk vervuild met magnesiumionen, die in het kristalrooster van calciet calciumionen kunnen vervangen.

Carbonates are compounds formed between a metal and the carbonate ion, (CO 3) 2-. When a carbonate decomposes, a metal oxide and carbon dioxide gas are produced. The general pattern of a decomposition of a carbonate reaction is: MCO 3--> MO + CO 2 (M is used to represent the metal. CO 3 is carbonate.) Look at the example below. Example #1:
