The precipitate formed is Calcium Carbonate (CaCO3).
X is an acid. The acid reacts with Calcium Carbonate producing carbon dioxide. When this is bubbled through limewater, it produces a fine calcium carbonate precipitate giving a milky appearance to the limewater.
When carbon dioxide is bubbled through it, they react together to form calcium carbonate (CaCO3) CO2 + Ca(OH)2 ---> CaCO3 + H2O This is the white precipitate
Lime water is calcium hydroxide. When carbon dioxide is bubbled through it forms this precipitate called as calcium carbonate. This doesnt dissole in the water so the lime water bexomes milky.
Calcium hydroxide solution is used to detect the presence of carbon bi oxide. When carbon bi oxide is passed through the solution of calcium hydroxide, it turns milky white. There is formation of calcium carbonate particle. This is what was taught to me as a kid in my school.
Trap the gas produced and bubble through lime solution (aqueous calcium hydroxide), if a cloudy precipitate is produced from the initially clear solution this proves that carbon dioxide was evolved.Ca(OH)2 (aq) + CO2 (g) → CaCO3 (s) + H2O (l)
Bubble the gas through limewater (calcium hydroxide), and then a white precipitate is formed, which is actually calcium carbonate.
When carbon dioxide gas is passed/bubbled through aqueous calcium hydroxide (also known as 'limewater'), a white precipitate will be formed. This means that the solution will turn cloudy/milky due to the formation of that white precipitate.Ca(OH)2(aq) + CO2(g) → CaCO3(s) + H2O(l)The precipitate, calcium carbonate, is only sparingly soluble in water. It will exist as a suspension in the resulting solution.But when excess carbon dioxide is added, this reaction takes place instead:CaCO3(s) + H2O(l) + CO2(g) → Ca(HCO3)2(aq)The calcium carbonate undergoes further reaction with water and carbon dioxide to form calcium bicarbonate (or calcium hydrogen carbonate), which is soluble. Thus the precipitate appears to 'disappear' or 'dissolve'. Thus, a colourless solution is formed.----- Other answers -----Water is added to give calcium hydroxide, and carbon dioxide is passed through this solution to precipitate the desired calcium carbonate, referred to in the industry as precipitated calcium carbonate (PCC):if carbon dioxide is passed through it it will turn cloudy and if it is done for to long then it will turn colourless.

You will see a preciptate of Calcium Carbonate [CaCO3] The Calcium Hydroxied is said to turn 'Milky' or 'Chalky' The chalkyness so described is the water insoluble Calcium Carbonate being deposited as it is formed.
Lime water is Ca(OH)2. When CO2 is bubbled, a white precipitate of CaCO3 (calcium carbonate) is formed.
When carbon dioxide is bubbled through it, they react together to form calcium carbonate (CaCO3) CO2 + Ca(OH)2 ---> CaCO3 + H2O This is the white precipitate

Calcium carbonate, formula of this: CaCO3
Bubble gas through limewater (saturated calcium hydroxide solution). The presence of carbon dioxide is indicated by the solution turning milky/cloudy. This is caused by the carbon dioxide and calcium hydroxide reacting to produce calcium carbonate which is insoluble, and is therefore seen as a white precipitate.
Lime water is calcium hydroxide. When carbon dioxide is bubbled through it forms this precipitate called as calcium carbonate. This doesnt dissole in the water so the lime water bexomes milky.
the precipitate calcium carbonate (CaCO3) is formed
A precipitate of calcium carbonate is formed.
