best way of testing for Carbon dioxide is to bubble it through lime water. ... Lime water turns milky as the Calcium hydroxide (chemical name for limewater) reacts with carbon dioxide to form Calcium Carbonate which is insoluble in water and thus forms a milky white precipitate.

Good morning dear......
Carbon dioxide (CO2) is colorless and odorless, so you can't detect it through direct observation. You'll need to collect an air sample (or a CO2 sample), then run one of several simple tests to identify the presence of the gas. You can bubble the gas through limewater, or you can hold a lit splint into the sample to see if it is extinguished by the presence of CO2.
