Neutralisation reaction.
With a carbon dioxide detector, meter, or gauge. If oxygen levels and dangerously low and carbon dioxide dangerously high you will have trouble breathing. -written by a weirdo With a carbon dioxide detector, meter, or gauge.

The equation is Ca(OH)2 + CO2 = CaCO3 + H2O.
Absorbed carbon dioxide in calcium hydroxide produce calcium carbonate, a white precipitate.
One reaction is calcium carbonate is calcium oxide plus carbon dioxide. Another reaction is carbon plus oxygen which equals carbon dioxide.
Carbon dioxide dissolves in water and reacts with the water to form carbonic acid, and therefore, you get an acid-base neutralization reaction with sodium hydroxide.
Calcium hydroxide is used to test for carbon dioxide because the product of the reaction, calcium carbonate, is insoluble, and easily visible.
If you think to calcium hydroxide, after the reaction with carbon dioxide calcium carbonate (CaCO3) is obtained.
Carbon dioxide is absorbed in calcium hydroxide and other hydroxides.
lime water (calcium hydroxide) turns milky when carbon dioxide is present
It is called a double replacement reaction.

calcium hydroxide + carbon dioxide = calcium carbonate + water
The equation is Ca(OH)2 + CO2 = CaCO3 + H2O.
Absorbed carbon dioxide in calcium hydroxide produce calcium carbonate, a white precipitate.
Calcium ydroxide is just another word for "Limewater". Limewater turns milky in the presence of Carbon Dioxide.
For example hydroxides as calcium, sodium or potassium hydroxide.
The carbon dioxide forms a precipitate with the calcium hydroxide. (Lime water is just a solution of calcium hydroxide) This precipiate is what makes it look chalky
