When CO₂ is passed through lime water for a short duration, it turns lime water milky due to the formation of a white precipitate of calcium carbonate.
Ca(OH) + CO₂ → CaCO₃ + H₂O
When CO₂ is passed through lime water for a long time, then white precipitate of calcium carbonate which was formed initially dissolves due to the formation of soluble calcium hydrogen carbonate and solution becomes clear again.
CO₂ + CaCO₃+ H₂O → Ca(HCO₃)₂
