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.

Calcium Carbonate | Wine Making Additive

Calcium Carbonate will help to reduce this sharp taste and unpleasant burning by lowering the amount of acid in the wine to a normal level. It does so by neutralizing the acid and causing it to drop out of the wine in the form of tiny crystals. The wine is then simply racked off the sediment deposits.
