When CO2 is passed through lime water milky white precipitate is formed because of the formation of "CALCIUM CARBONATE"

Clear, colorless limewater absorbs carbon dioxide readily from air, giving a milky solution. This is due to the insoluble suspension of calcium carbonate formed:

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)
