When carbon dioxide (CO2) is passed through lime water (a saturated solution of calcium hydroxide, Ca(OH)2) for an extended period, it reacts with the calcium hydroxide to form calcium carbonate (CaCO3), which is a white precipitate. Initially, the lime water turns milky due to the formation of this precipitate. Over time, if excess CO2 is introduced, the precipitate can dissolve back into the solution, forming calcium bicarbonate, which is soluble in water.

What happens when conbon dioxide is passed through water?
When carbon dioxide is passed through lime water it will turn milky.
What happens when carbon dioxide gas is passed through lime water in excess?
When carbon dioxide gas is passed through lime water in excess, the lime water turns milky due to the formation of calcium carbonate (CaCO3) as a white precipitate. This reaction is used as a test for the presence of carbon dioxide gas.
When co2 is passed through lime water?
The lime water turns milky.
What happens when access carbon Di oxide passed through lime water?
Lime water is Ca(OH)2. When CO2 is bubbled, a white precipitate of CaCO3 (calcium carbonate) is formed.
What is the test for co2 gas?
When carbon dioxide is passed through lime water it goes cloudy.

When co2 is passed through lime water?
The lime water turns milky.
What happens when access carbon Di oxide passed through lime water?
Lime water is Ca(OH)2. When CO2 is bubbled, a white precipitate of CaCO3 (calcium carbonate) is formed.
What happens when carbon dioxide is passed through lime water in small amount?
A slurry of calcium carbonate is formed.
What happens when hydrogen gas is passed through lime water?
When hydrogen gas is passed through lime water, no immediate change will be observed. Lime water is a solution of calcium hydroxide, which is basic. Since hydrogen gas is neutral, it does not react with lime water to produce a visible change.
What happens when carbon di oxide passes through lime water?
Carbon dioxide turns lime water milky.
What is the test for co2 gas?
When carbon dioxide is passed through lime water it goes cloudy.
What happens when lime juice is mixed with water?
lime flavored water.
What happens when chlorine gas is passed through lime water?
When chlorine is passed through dry slaked lime power Ca(OH)2 , bleaching powder is obtained .Slaked lime --- Ca(OH)2 Chlorine --- Cl2The chemical equn :- Ca(OH)2 + Cl2 ------> CaOCl2 + H2OCaOCl2 is bleaching powderThe three properties Of bleaching powder , (CaOCl2) areIt is a yellowish white powder with a strong smell of chlorineIt reacts with carbon dioxide , dil. HCl and di. H2SO4 to form chlorine gas.It is soluble in water but since it is generally contaminated with Ca(OH)2 , it may produce a milky solution
What happens to lime-water if carbon dioxide is bubbled through it and heated?
It turns cloudy white.
What happen when chlorine gas is passed through dry slaked lime?
When chlorine gas is passed through dry slaked lime, it reacts with the calcium hydroxide in the lime to form calcium hypochlorite, which is a bleaching agent and disinfectant. This reaction also releases heat and forms calcium chloride and water as byproducts.
