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.

However, calcium carbonate is more likely to affect the flavor than potassium carbonate, and may take a few months to fully precipitate. One-quarter ounce (about 4 teaspoons) reduces acidity in one gallon by about 0.25%. Foaming may occur because of the production of CO2. Do not use more than one ounce per gallon. Wait 24 hours and rack wine. Also used in beer to increase the temporary ...
