Why does lime water change?
Lime water is nothing but calcium oxide. It is so transperent. When we blow air through it using a straw, then it becomes milky ie white. This is because of formation of calcium carbonate as carbon di oxide right from our blowing air reacts with calcium oxide.
When we blow air through the freshly prepared lime water how much time does lime water takes to turn milky?
It will depend on the amt of CO2 was passed
Is h2co3 soluble?
YES!!! It is!!! It is formed when carbon dioxide is dissolved in water. CO2 + H2O = H2CO3 (Carbonic Acid).
What happend when you mix carbon dioxide with lime water?
Lime water reacts with carbon dioxide to produce a precipitate of calcium carbonate (CaCO3): Ca(OH)2 (aq) + CO2 (g) → CaCO3 (s) + H2O (l) As you can see, it also produces water (H20). Thus, lime water can be used to detect the presence of carbon dioxide.
Does lime has calcium content?
yes it is found in lime yes it is found in lime.
What happens when you blow a straw into lime water?
It becomes milky, indicating the presence of Carbondioxide.

What do you observe when carbon dioxide enters line water?
If you mean "what is observed when carbon dioxide enters lime water" then lime water, or calcium carbonate (CaCO3) absorbs carbon dioxide (CO2) to form a white precipitate or "milky" solution that is semitransparent.
How would you use lime water to test if there is carbon dioxide in your exhaled breath?
when lime water react with carbon dioxide,it turns milky.So, we have to take some lime water in a test tube and exhale 2 -3 times to the test tube through a bend tube. It will turn milky and that's why our exhaled breath is carbon dioxide.
What is the difference between quick lime and lime water?
Quick lime is calcium oxide, CaO. Lime water is calcium hydroxide, Ca(OH)2 dissolved in water. Lime water can be made by dissolving quick lime in water.
When few pieces of marble is dropped in dilute hydrochloric acid the evolved gas passed through lime water what change would be observed in lime water so what will be the balanced chemical equation?
The chemical equation is:Ca(OH)2 + CO2 = CaCO3 + H2O

How do you get limestone from quicklime?
Take a small quantity of quicklime (CaO) in a beaker and add a small quantity of water into it. Quicklime reacts vigorously with water to form a suspension of slaked lime (Ca(OH)2) in water. CaO + H2O = Ca(OH)2 Then leave the beaker containing slaked lime undisturbed for some time. After some time a clear solution is obtained as the suspension of slaked lime settles down. This clear solution is called lime water. Then take the lime water in a test tube and pass CO2 gas through it (or blow exhaled air into the lime water through a glass tube). The lime water turns milky. CO2 gas reacts with lime water to form a white precipitate of calcium carbonate. This white precipitate is called lime stone Ca(OH)2 + CO2 = CaCO3 + H2O
How do you clean a liquid sprayer after using liquid lime solution?
Wash it out with fresh water several times and make sure you blow clean water through the spray nozzle.
What would be the effect of the gas on lime water?
Gas (I assume you mean air ) contains Carbon dioxide and if you blow Carbon Dioxide into Lime Water, it turns it milky due to the formation of insoluble CaCO3 The equation is Ca(OH)2 + CO2 = CaCO3 + H20
