Powdered calcium carbonate reacts with dilute hydrochloric acid to produce calcium chloride, water and carbon dioxide. What is the correct ionic equation, including state symbols, for this reaction?

  1. ACaCO3(s) + 2HCl(aq) → CaCl2(aq) + H2O(l) + CO2(g)
  2. BCa2+(aq) + CO3^2–(aq) + 2H+(aq) → Ca2+(aq) + H2O(l) + CO2(g)
  3. CCO3^2–(aq) + 2H+(aq) → H2O(l) + CO2(g)
  4. DCaCO3(s) + 2H+(aq) → Ca2+(aq) + H2O(l) + CO2(g)
