When you breathe out, Carbon Dioxide (CO2) is released. This reacts with the limewater to form a precipitate of calcium carbonate which appears as a white semitransparent substance in the solution.
Because of this phenomenon, limewater is offen used in chemistry as an indicator of Carbon Dioxide. The equation (found on Wikipedia) is here below:
Ca(OH)2 (aq) + CO2 (g) => CaCO3 (s) + H2O (l)

∙ 12y agoBy carbon dioxide accesss through this reaction (excess of hydroxide needed):
Ca2+ + 2OH- + CO2,g --> CaCO3,s + H2O
However more carbon dioxide may clear it up again (only under absence of hydroxide):
CaCO3,s + H2O + CO2,g --> Ca2+ + 2HCO3-

∙ 12y agoActually, limewater does not turn chalky but it turns milky, to be precise. It is due to the mixing of carbon dioxide that is CO2, with limewater that is Ca[OH]2 which results in the formation of Calcium Carbonate that is CaCO3. The reaction is as follows:
Ca[OH]2 ( Lime Water) + CO2 ( Carbon Dioxide ) --> CaCO3 ( Calcium Carbonate)

∙ 12y agoWhen carbon dioxide is bubbled through lime water, it can react with the lime to form calcium carbonate, and this forms as a solid in small particles that make the water appear cloudy.

Why does exhaled air turn limewater chalky faster than inhaled water?
carbon dioxide turns lime water chalky. the more carbon dioxide, the faster the limewater turns chalky. Exhaled air contains carbon dioxide waste from the bodies organs, and that's why it contains more carbon dioxide than inhaled air.
How are RNA hairpin turns related to termination?
The turns are formed from complementary base pairing and cause separation of the RNA transcript and RNA polymerase.
What is chalky mouth a symptom of?
while eating my dinner I got a very chalky mouth feeling. Only new thing I put in the dinner is chickpeas Some foods (such as chickpeas) can have an astringent effect on the mouth while eating them. It's temporary, and can be remedied by drinking lots of water.
If biuret reagent turns purple what substance is present?
food that has protein like milk will cause the Biuret solution to turn purple.
What does it mean when the below the nose turns white?
Raynaud's disease is a condition when the skin below the nose turns white. It may also affect the fingers, toes, and ears. This is caused by cold temperatures or strong emotions that cause the blood vessel spasms.
Does carbon dioxide turn limewater chalky and why?
it turns into a milky solution
Will oxygen turn limewater chalky?
no,it will not. carbon dioxide ill thurn limewater chalky..:)
Does nitrogen turn limewater chalky?
Yes
If a plant is put into limewater in a testube which is sealed and left overnight Will the limewater become very chalky?
Of cousethe plant sets off CO2 which reacts with ca(oh)2 exists in limewater engender caco3so the limewater will become chalky
What would happen if you put pond snails in limewater?
Snail breathes, CO2 add Lime water = Limewater turns chalky white
What liquid take in oxygen will became chalky?
Limewater
What causes limewater to turn chalky in the presence of carbon dioxide?
No
What happens to limewater in the presence of carbon?
it will become milky and chalky
Why does exhaled air turn limewater chalky faster than inhaled water?
carbon dioxide turns lime water chalky. the more carbon dioxide, the faster the limewater turns chalky. Exhaled air contains carbon dioxide waste from the bodies organs, and that's why it contains more carbon dioxide than inhaled air.
What is the property of a limewater?
Limewater turns milky when CO2 gas is passed through it.
What is the test for dioxide?
Bubbling through limewater. The gas is present if the limewater turns cloudy :)
If I put two plants into two boxes make of clear glass and wood along with some limewater why would the limewater in the wooden box turns chalky but not the limewater in the clearglass?
The plant in the wooden box has no light, so it cannot photosynthesize. The plant in the dark will still respire and so produce carbon dioxide, indicated by the limewater going milky. The plant in the clear glass box will use up any carbon dioxide and produce oxygen instead.
