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)

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 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.
Do plants need limewater to photosynthesis?
Plants do not require limewater to photosynthesize. Photosynthesis primarily involves extracting carbon dioxide from the air and converting it into glucose using energy from sunlight. Lime or limewater is used by plants mainly to adjust soil pH and provide calcium for healthy growth, but it is not directly involved in the photosynthesis process.
If biuret reagent turns purple what substance is present?
Proteins are present when biuret reagent turns purple. Biuret reagent reacts with peptide bonds in proteins, causing the color change.
How are RNA hairpin turns related to termination?
RNA hairpin turns contain a termination signal that is recognized by specific proteins involved in termination of transcription. When RNA polymerase encounters this signal, it triggers the release of the RNA transcript and dissociation of the RNA polymerase from the DNA template, marking the end of transcription.
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?
No, nitrogen does not turn limewater chalky. Chalky precipitates in limewater are a result of carbon dioxide reacting with calcium hydroxide to form calcium carbonate. Nitrogen does not participate in this reaction.
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 liquid take in oxygen will became chalky?
Limewater
What causes limewater to turn chalky in the presence of carbon dioxide?
No
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 test for dioxide?
Bubbling through limewater. The gas is present if the limewater turns cloudy :)
Does the air around us turn limewater chalky?
yes the air around turns the lime water chalky. It is due to the formation of calcium carbonate from lime water due to its reaction with atmospheric air which contains carbondioxide. the chemical reaction for the phenomenon is as follows Ca(OH)2+co2 =CaCO3+H2O
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.
What test would allow you to tell the difference between carbon dioxide and nitrogen?
The limewater test can differentiate between carbon dioxide and nitrogen. When carbon dioxide is bubbled through limewater, it turns milky due to the formation of calcium carbonate. Nitrogen will not have this effect on limewater.
What would happen if you put pond snails in limewater?
Snail breathes, CO2 add Lime water = Limewater turns chalky white
