Calcium carbonate (limestone, CaCO3) dissolves in hydrochloric acid, producing water and carbon dioxide as shown in the following unbalanced net ionic equation:
CaCO3(s) + H3O+(aq) → H2O(ℓ) + CO2(g) + Ca2+(aq)
Suppose 1.1 g of CaCO3 is added to 500 mL of 0.10 M HCl. What is the maximum mass of CO2 that could be formed? What would the final concentration of Ca2+ ions be? (Assume that the final solution volume is still 500 mL.)
g CO2
M Ca2+
