Calcium Carbonate To Calcium Oxide

Reactions of calcium carbonate Physics Forums

· Calcium carbonate will react with water that is saturated with carbon dioxide to form the soluble calcium bicarbonate. caco3 + co2 + h2o → ca(hco3)2 What role does CO2 play in that reaction because, as you have just shown me, that reaction happens anyway in two steps without co2:

Thermal decomposition of calcium carbonate (13K)

Copper carbonate decomposes easily on heating to make copper oxide and carbon dioxide. Calcium carbonate needs a higher temperature to make it decompose than copper carbonate does – you must supply more heat. Today, you will be studying the thermal decomposition of calcium carbonate. Marble and limestone are both forms of calcium carbonate.

Facts That Are Notable About Calcium Carbonate

However, calcium carbonate is made from oxides of calcium. Calcium oxide is dissolved in water to form calcium hydroxide. To precipitate the desired solution carbon dioxide is passed through calcium hydroxide which is signified as precipitated calcium carbonate (PPC). CaO + H 2 O -> Ca (OH) 2. Calcium oxide + Water → Calcium hydroxide
