When Carbon dioxide gas is passed through lime water it turns milky due to formation of insoluble calcium carbonate ( white precipitate).Ca(OH)2+ CO2 ---> CaCO3 + H2O ( White precipitate) On passing excess CO2 the white precipitate disappeares as soluble calcium​ bicarbonate is formed.CaCO3 + CO2 + H2O---> Ca(HCO3)2 (excess) (Soluble)
