Lime water turns milky when CO2 (carbon dioxide) is passed through it. So to test if a given liquid is lime water, pass CO2 through it, if it turns milky, then it is limewater. You can reverse this chemical reaction by putting vinegar in it.
Freshly prepared lime water is used in the evperiment to test the presence of CO2 in water because lime water turns milky when CO2 is present in water.
when lime water react with carbon dioxide,it turns milky.So, we have to take some lime water in a test tube and exhale 2 -3 times to the test tube through a bend tube. It will turn milky and that's why our exhaled breath is carbon dioxide.
Quick lime is calcium oxide, CaO. Lime water is calcium hydroxide, Ca(OH)2 dissolved in water. Lime water can be made by dissolving quick lime in water.
When you slake a lime an leave it for a few months, there will be a layer of water (providing you used a sufficient amount) ontop of the slaked lime putty. this water is limewater and is clear but contains tiny particles in suspension. The putty is what we refer to as slaked lime.
If it's exposed to pure oxygen then nothing will happen. If it's exposed to air then the carbon dioxide in air will make it go cloudy. Lime water is the test for the presence of carbon dioxide.
Lime water turns milky when CO2 (carbon dioxide) is passed thru it. So to test if a given liquid is lime water, then pass CO2 thru it, if it turns milky, d liquid is lime water...

Lime water test.
Because when lime water is used to test for the presence of carbon dioxide, it will turn cloudy if the result is positive.
You can test it with the Lime Water test. If there is carbon dioxide in your breath then the Lime Water should turn cloudy.
add lime water to the air if the lime water turns cloudy then carbon dioxide is present
Get a test tube filled with lime water, then breathe into the test tube and if the lime water turns a milky white colour then there is carbon dioxide present!

Test it with lime water. If the lime water goes milky you have carbon dioxide.
Put the gas (CO2) in lime water. If the lime water changes colour, then it means that there is carbon dioxide in the gas depending on how fast the lime water changes colour
It is to test for the presence of carbon dioxide. If carbon dioxide is present,it will turn chalky however if carbon dioxide is absent,lime water will remain colourless.
