Calcium carbonate CaCO3 Reactions
2021-5-10 Methods for preparation of calcium carbonate: CaO + CO2 = CaCO3 (normal temp.). Ca (OH)2 + EO2 = CaEO3 + H2O (E = C, S), Ca (OH)2 (suspension) + 2EO2 = Ca (HEO2)2 (solution). CaCl2 + Na2CO3 = CaCO3↓ + 2NaCl. Chemical reactions with calcium carbonate: CaCO3 = CaO + CO2 (900-1200° C). CaCO3 + 2HCl (diluted) = CaCl2 + CO2↑ + H2O.
