Ha ha ha well lime water is simply Calciumhydroxide Ca(OH)2 it is a colorless solution and well it is basic/ alkaline coz of varrious reasons some of which are it turns red litmus blue and can react whit acids through a neutralization reaction.
Anyway you basically wanted to know what it is used for. Ha ha ha Lime water is used to test for presence of Carbondioxide in the lab when Carbondioxide passes through it turns from colorless to cloudy white substance which is called Calcium Carbonate
Ca(OH)2 + CO2 ----> CaCO3 + H2O

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
