but excessive consumption can be hazardous. Calcium carbonate shares the typical properties of other carbonates. Notably: it reacts with strong acids releasing carbon dioxide: CaCO3(s) + 2 HCl(aq) → CaCl2(aq) + CO2(g) + H2O(l) it releases carbon dioxide on heating called a ...
Calcium carbonate produces a potent and prolonged neutralization of HCl forming CO2 and CaCl2. Approximately 90% of the ingested Ca2+ forms insoluble salts in the gut and is excreted in the feces. The remaining Ca2+ is absorbed into the systemic circulation. Extensive use of Ca2+-containing ant...
