Answered by sanapalassb

Answer:

When excess of carbon dioxide gas is passed through lime water then the white precipitate calcium carbonate formed first dissolves due to the formation of a soluble salt calcium hydrogen carbonate (Ca(HCO3)2, and the Solution becomes clear again. CaCO3 (s) + H2O(l) + CO2(g) ------> Ca(HCO3)2.
