Lime water is the name of a mineral known as lime (a chemical called calcium oxide / CaO). ammonia . CaCO 3 (s) + H 2 O (l) + CO 2 (g) → Ca(HCO 3) 2 (aq). You put lime water into a test tube of carbon dioxide and if it turns milky it shows that their is carbon dioxide present. ( I had also moved the lime water to a smaller beaker to make the liquid deeper and more likely to absorb the carbon dioxide.) answr. When CO 2 is passed through lime water for a short duration, it turns lime water milky due to the formation of a white precipitate of calcium carbonate.
