The products are calcium carbonate(CaCO3) and water(H2O).
The solution is calcium carbonate solution

Limewater + Carbon Dioxide ==> Chalk(/Limestone) + Water :

Ca(OH)2(aq) + CO2(g) ==> CaCO3(s) + H2O(l)

Yes. What happens is that the CO2 from your breath reacts w/ the limewater (calcium hydroxide) to form water and calcium carbonate. The calcium carbonate is the solid stuff that makes it look cloudy. The reaction is: 2Ca(OH)2 + 2CO2 ==> 2CaCO3 + H2O

The chalky limewater turns clear after a while because the heavy chalk particles begins to settle down. Anyway, i rated the 1st person because she gave a good answer.

lime water turns milky
as calcium hydroxide to form calsium carbonate which is a precipitate ,hence the solution turns milky

The lime water after some turns back to clear is becoz CaHCo3 which is soluble in water.
