Question

balanced equation for the following reaction carbon dioxide is passed through lime water

Answer 1

Carbon dioxide passed into limewatergives a milky solution, due to precipitation of an insoluble suspension of calcium carbonate: Ca(OH)2(aq) + CO2(g) → CaCO3(s) + H2O(l) If excess CO2 is added, the following reaction takes place: CaCO3(s) + H2O(l) + CO2(g) → Ca(HCO3)2(aq)
