Chemically, calcium carbonate is prepared with several chemical changes. Firstly, add water to quicklime (CaO) to produce calcium hydroxide (Ca (OH)2). And then the calcium hydroxide react with carbon dioxide to precipitate the calcium carbonate, and so the end product is called precipitated calcium carbonate.
