Web9 de abr. de 2024 · There is also another method to obtain the calcite by adding sodium carbonate to calcium chloride. CaCl2 + Na2CO3 → CaCO3 + 2NaCl Ca (OH)2 + CO2 → CaCO3 + H2O When carbon dioxide is passed in excess amounts, it leads to the formation of calcium hydrogen-carbonate. Calcium carbonate shares the typical properties of other carbonates. Notably it reacts with acids, releasing carbon dioxide (technically speaking, carbonic acid, but that disintegrates quickly to CO2 and H2O): $${\displaystyle {\ce {CaCO_3(s) {+}2H^{+}(aq) -> Ca^{2+}(aq) + CO2(g) + H_2O(l)}}}$$ … Ver más Calcium carbonate is a chemical compound with the chemical formula CaCO3.
