If you blow air into lime water with a straw, the lime water will turn milky due to the formation of calcium carbonate, which is insoluble and creates a precipitate. This reaction occurs as carbon dioxide in the exhaled air reacts with the calcium hydroxide in the lime water to form calcium carbonate.
What else can I help you with?
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.
What is the symbol for lime water?
The symbol for lime water is Ca(OH)2. Lime water is a saturated solution of calcium hydroxide in water.
Does lime has calcium content?
yes it is found in lime yes it is found in lime.
When co2 is passed through lime water?
The lime water turns milky.
Is h2co3 soluble?
yes to a certain degree, it makes slaked lime when added to excess water it can make lime water which turns milky when you blow air through it
What happens when you blow a straw into lime water?
It becomes milky, indicating the presence of Carbondioxide.
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 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.
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.
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.
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
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 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
What is the symbol for lime water?
The symbol for lime water is Ca(OH)2. Lime water is a saturated solution of calcium hydroxide in water.
What is the difference between slaked lime and lime water?
When you slake a lime an leave it for a few months, there will be a layer of water (providing you used a sufficient amount) ontop of the slaked lime putty. this water is limewater and is clear but contains tiny particles in suspension. The putty is what we refer to as slaked lime.
Is lime water acidic or alkaline?
Lime water is alkaline.
