The white ppt is Calcium Carbonate. You bubble Carbon Dioxide into Calcium Hydroxide. If you continue bubbling Carbon Dioxide the solution becomes clear again. The calcium carbonate becomes Calcium hydrogen carbonate which is clear. This is reversible by Boiling.

I think the solution you're bubbling the carbon dioxide into is calcium hydroxide.
When you bubble carbon dioxide through this solution, a chemical reaction takes place which produced calcium carbonate - that's the white precipitate you see.

The whilte precipitate that is formed when carbon dioide is bubbled through lime water is calcium carbonate, the equaton is below:
Ca(OH)2(aq) + CO2 (g) ---------> CaCO3(s) + H2O (l)

erm, calcium carbonate IS the ppt when you bubble CO2 into limewater.

CO2 is the white precipitate. It onli reacts to form a white colour
