Carbon dioxide passed into limewater gives a milky solution. This is due to the formation of calcium carbonate which is insoluble in water. Ca(OH)2 (aq) + CO2 (g) —> CaCO3 (s) + H2O(l) However, when excess of carbon dioxide is passed through the solution, the turbidity disappears and a clear solution is obtained due to the formation of calcium carbonate which is soluble in water.
