What else can I help you with?
Why is the presence of oxygen determined by passing it through lime water?
It isn't. Bubbling gas through limewater is a test for the presence of carbon dioxide. If the gas contains carbon dioxide, then the clear solution of limewater will turn a cloudy white.
When co2 is passed through lime water?
The lime water turns 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.
What happens when conbon dioxide is passed through water?
When carbon dioxide is passed through lime water it will turn milky.
What will happen if you continue to pass carbon dioxide through lime water?
nothing!

What happens when carbon di oxide passes through lime water?
Carbon dioxide turns lime water milky.

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.
What type of rock is usually identified with layers?
Lime
If you collect gas from a dead animal and bubble it through lime water the lime water turns cloudy what is the gas?
The gas collected from the dead animal and bubbled through lime water is likely carbon dioxide (CO2). This gas reacts with the lime water (calcium hydroxide) to form calcium carbonate, which is insoluble and appears as a cloudy white precipitate.
How do you perform the lime water test?
Lime water turns milky when CO2 (carbon dioxide) is passed through it. So to test if a given liquid is lime water, pass CO2 through it, if it turns milky, then it is limewater. You can reverse this chemical reaction by putting vinegar in it.
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 conbon dioxide is passed through water?
When carbon dioxide is passed through lime water it will turn milky.
Write a procedure for distinguishing between oxygen gas and carbon dioxide gas?
If carbon dioxide and oxygen are bubbled through lime water separately the lime water through which carbon dioxide has been bubbled turns milky while the lime water through which oxygen is bubbled remains unaffected.
What will happen if you continue to pass carbon dioxide through lime water?
nothing!
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
