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

The calcium carbonate is used to remove excess acid from juices (which does raise the pH). As long as the wine is high in acidity and needs the acidity lowered, it will help the taste/quality of the wine. If you use more than the recommended dosage, the wine will have a chalky taste.

Calcium carbonate, for example, is often found precipitating in proximity to hot springs. In contrast, carbon dioxide is more soluble in cold water than in warm. In the deep ocean basins (water depths greater than about 11,000 meters), equation [2] is shifted so as to produce more carbonic acid which results in a shift to the right in equation [1] resulting in the solution of calcite.
