Carbon dioxide test. Test tube of limewater with carbon dioxide gas being bubbled through. The limewater, a solution of calcium hydroxide in water, is turning milky. This is used as a test for the presence of carbon dioxide. The reaction between limewater and carbon dioxide produces calcium carbonate as a white solid (precipitate). The equation for the reaction is CO2 + Ca(OH)2 ---> CaCO3 + H2O.
