When you blow air into the lime water with a straw what is observed?

∙ 13y ago
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.

Why does lime water change?
Lime water changes color due to the reaction between the calcium hydroxide in the water and carbon dioxide in the air, forming calcium carbonate, which gives the solution a milky appearance. This change is a chemical reaction that is commonly used in chemistry experiments to test for the presence of carbon dioxide.
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.
Is h2co3 soluble?
Yes, H2CO3 (carbonic acid) is soluble in water. It forms a weak acidic solution when dissolved in water.
When co2 is passed through lime water?
The lime water turns milky.
What happens when you blow a straw into lime water?
It becomes milky, indicating the presence of Carbondioxide.
Why does lime water change?

This change is a chemical reaction that is commonly used in chemistry experiments to test for the presence of carbon dioxide.
When we blow air through the freshly prepared lime water how much time does lime water takes to turn milky?
When air containing carbon dioxide is blown through fresh lime water, it will turn milky due to the formation of a white precipitate of calcium carbonate. This usually happens almost immediately, within a few seconds to a minute, depending on the concentration of the carbon dioxide in the air being blown.
How would you use lime water to test if there is carbon dioxide in your exhaled breath?
You would exhale into a straw placed in a container of lime water. If there is carbon dioxide in your breath, the lime water will turn cloudy or milky due to the formation of calcium carbonate precipitate. This reaction indicates the presence of carbon dioxide in your exhaled breath.
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.
What happend when you mix carbon dioxide with lime water?
When carbon dioxide is mixed with lime water (calcium hydroxide solution), it forms a milky white precipitate of calcium carbonate. This is because the carbon dioxide reacts with the calcium hydroxide to form calcium carbonate, which is insoluble in water. This reaction is often used as a test for the presence of carbon dioxide.
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
What observed when air is passed into fresh lime water through injection answer in chemistry?
Calcium hydroxide react with traces of carbon dioxide from the air, forming the white insoluble in water calciun carbonate.
