1. when CO2 is passed through lime water Ca(OH)2 for a short period of time... the following reaction takes place and lime water turns milky due to the formation of white precipitate
Ca(OH)2 + CO2 ---> CaCO3 + H2O
2. when CO2 is passed through lime water Ca(OH)2 for a considerable time, then the white precipitate of CaCO3 dissolves due to formation of a soluble salt calcium hydrogen carbonate and the solution becomes clear again
CaCO3 + CO2 + H2O ---> Ca(HCO3)2
Ca(OH)2 + CO2 ---> CaCO3 + H2O

Hey,
lime water is nothing but calcium hydroxide in water.
when Carbon dioxide is passed in to lime water, the carbon dioxide reacts with Calcium hydroxide to form a white precipitate
This white precipitate is nothing but calcium carbonate.
Refer to image attached.
HOPE THIS HELPS YOU.
