CO2 is passed through lime water which initially turns the solution milky because of formation of calcium carbonate. On continuous bubbling of CO2 the solution becomes clear due to the formation of calcium bicarbonate. underset text Lime water Ca ( OH )2+ CO 2 arrow underset text (Milky) CaCO 3 downarrow+ H 2 O underset textExcessCaCO 3+ CO 2+ H 2 O arrow underset textCalcium bicarbonate (Soluble in water)Ca ( HCO 3)2(a q)
