lime water is calcium hydroxide Ca(OH)2
when CO2 is added
Ca(OH)2 + CO2 = CaCO3 + H2O CaCO3 is sparingly soluble in water and seems white
when CO2 is added
Ca(OH)2 + CO2 = CaCO3 + H2O CaCO3 is sparingly soluble in water and seems white

When carbon dioxide gas is passed through lime water for a considerable time ,then the white precipitate of calcium carbonate which is fomed initially as shown in the above reaction ,dissolves due to formation of a soluble salt calcium hydrogen carbonate and the solution becomes clear again.
The reaction is -
CaCO3 + CO2 + H2O → Ca(HCO3)2.
hope it helpt:)
