Final answer: To find the percent of CaCO3 by mass in the limestone, we calculate the mass percent composition of CaCO3 in the sample. We determine the mass of CaCO3 by calculating the moles of CO2 generated and using the molar mass of CO2 and CaCO3. Finally, we divide the mass of CaCO3 by the mass of the sample and …

Determination of Calcium Carbonate in Eggshells – Background

Calcium carbonate (limestone) is very insoluble in pure water but readily reacts in acid according to the reaction below. 2HCl(aq) + CaCO3(s) → CaCl2(aq) + CO2(g) + H2O(l) + HCl(aq) (in excess) (limiting reagent) (1) (unreacted) This reaction cannot be used directly to titrate the CaCO3 because it is very slow when the reaction is close to ...
