limewater is Ca(OH)2
the reason for CO2 to turn limewater milky is because
Ca(OH)2 (aq) + CO2 (g) → CaCO3 (s) + H2O (l)
the precipitate CaCO3 formed.
I think SO2 could also turn limewater milky because the product CaSO4 is only slightly soluble in water, so most of it remains as a precipitate.
Ca(OH)2 + SO2 ---> CaSO4 + H2O

Limewater is a solution of Calcium hydrate in water, also known as slaked lime. The more quicklime (calcium oxide) that is slaked, the more white and the more caustic it becomes.
Calcium carbonate (limestone) and high heat (in a kiln) = Calcium oxide and CO2
Calcium oxide (quicklime) and water = calcium hydrate (slaked lime)
slaked lime and water = lime water

Lime water is an aqueous solution of calcium hydroxide; Ca(OH)2. When carbon dioxide is introduced, it reacts with the calcium hydroxide and produces a solid precipitate of calcium carbonate; CaCO3 and water. The solid precipitate is what causes the lime water to look cloudy.

CO2 + Ca(OH)2 -----> CaCO3 + H2O
CaCO3 is formed as a white precipitate, which is why limewater turns milky.

What is the property of a limewater?
Limewater turns milky when CO2 gas is passed through it.
Lime water turns milky in the presence of?
limewater turns milky because when co2 reacts with it the particles make it luk cloudy and milky........... ********************************* And you could add that the cloudy appearance is due to the formation of CaCO3, which is insoluble in water.
How do you test for presence of carbonate ion?
Reagent: Add dilute Hydrochloric acid [HCl] Inference: Effervescence and a gas which turns limewater milky [CO2 ] Equation: CO32- +2H+ -> H2O + CO2
How do you perform the lime water test?
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.
What happens to limewater in the presence of carbon?
it will become milky and chalky
What is the property of a limewater?
Limewater turns milky when CO2 gas is passed through it.
A gas that turns limewater milky and that you breathe out?
carbon dioxide formula: CO2 structure: O=C=O
Does carbon dioxide turn limewater chalky and why?
it turns into a milky solution
Does ammonia turn limewater milky?
I don't know , so unless ammonia has carbon dioxide present because limewater only turns milky when carbon dioxide is present
What is the test for dioxide?
Bubbling through limewater. The gas is present if the limewater turns cloudy :)
Why does limewater go milky?
Limewater get milky at the presence of carbon dioxide dissolved in it.
How do you test a gas to see if it was carbon dioxide?
Bubbling the gas into limewater is the classic test for CO2. Limewater is a saturated solution of Ca(OH)2. When CO2 is dissolved it reacts to produce insoluble CaCO3 and the solution turns cloudy. Ca(OH)2(aq) + CO2(aq) --> CaCO3(s) + H2O(l) :)
What is made of carbon and oxygen is used by plants and turns limewater milky?
This compound is carbon dioxide - CO2.
What test could you use to find out if CO2 gas is present in a small container?
Blow it through limewater. If the limewater turns "milky" or "cloudy" (a white substance is shown) then Carbon Dioxide is present. If nothing happens, then Carbon Dioxide is not present in your solution.
Lime water turns milky in the presence of?
limewater turns milky because when co2 reacts with it the particles make it luk cloudy and milky........... ********************************* And you could add that the cloudy appearance is due to the formation of CaCO3, which is insoluble in water.
What gas do we exhale that can be tested for using limewater?
Carbon Dioxide will change limewater (calcium hydroxide) into calcium carbonate. This shows as a white precipitation (milky).
How could the solid calcium hydroxide be used to test for carbon dioxide?
Calcium ydroxide is just another word for "Limewater". Limewater turns milky in the presence of Carbon Dioxide.
