Carbon dioxide. A lighted wooden splint goes out in a test tube of carbon dioxide but this happens with other gases, too. It is better to bubble the test gas through limewater - calcium hydroxidesolution. Carbon dioxide turns limewater cloudy white.

Well, lime water is simply Calcium hydroxide Ca(OH)2 it is a colorless solution and well it is basic/ alkaline cause of various 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. Lime water is used to test for presence of Carbon dioxide in the lab when Carbondioxide passes through it turns from colorless to cloudy white substance which is called Calcium Carbonate.
