When you blow air through a test tube of limewater (a saturated solution of calcium hydroxide), the carbon dioxide (CO2) in your breath reacts with the calcium hydroxide to form calcium carbonate, which is insoluble in water. This reaction causes the limewater to turn milky or cloudy, indicating the presence of carbon dioxide. This phenomenon is often used as a simple test for CO2. Over time, the cloudiness may settle as the calcium carbonate precipitates out of the solution.
What else can I help you with?
What is the test for carbon dioxide?
to test for carbon dioxide is already dissolved in limewater , after this shake up the test tube , is it be that carbondioxide is present then two things will happen : 1) the limewater will turn cloudy as co2 is a precipatate is this solution 2)the limewater will begin to show efferevescence now we know gas is present if these two thing happen then there is an extremly high chance that co2 is present.
What is the name of carbon dioxide gas test?
The test to detect the presence of carbon dioxide gas is called the limewater test. It involves passing the gas through limewater (a solution of calcium hydroxide) and observing a milky white precipitate forming if carbon dioxide is present.
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.
Does limewater absorb CO2?
Yes, limewater (calcium hydroxide solution) reacts with CO2 in the air to form insoluble calcium carbonate, causing the limewater to turn milky or cloudy. This reaction is often used as a test for the presence of CO2.
How do you test for carbon dioxide with a splint?
collect gas from reaction with a test tube, then light spint and insert into the gas filled tube. if splint is extinguished immediately, then its CO2. but limewater test is more reliable
What is the test for dioxide?
Bubbling through limewater. The gas is present if the limewater turns cloudy :)
What is the test for carbon dioxide?

Which liquid is used to test for carbon dioxide?
Carbon dioxide levels are tested through the blood
What test could you use to find out if CO2 gas is present in a small container?
Blow it through limewater. If the limewater turns "milky" or "cloudy" (a white substance is shown) then Carbon Dioxide is present. If nothing happens, then Carbon Dioxide is not present in your solution.
How do you do the limewater test?
Put the solution your testing CO2 for into a boiling tube. Put a plug with a tube leading out of it in the top of the boiling tube. Place the other end of the plugs tube into a beaker full of limewater. If carbon dioxide is present, the limewater will turn cloudy.
How do you test for carbon dioxide when calcium carbonate reacts with acid?
To test for carbon dioxide gas produced when calcium carbonate reacts with acid, you can bubble the gas through limewater. If carbon dioxide is present, it will turn the limewater cloudy or milky due to the formation of calcium carbonate.
What test would allow you to tell the difference between carbon dioxide and nitrogen?
The limewater test can differentiate between carbon dioxide and nitrogen. When carbon dioxide is bubbled through limewater, it turns milky due to the formation of calcium carbonate. Nitrogen will not have this effect on limewater.
What happens to the limewater if the gas is present?
If a gas is present in limewater, such as carbon dioxide, it will react with the limewater to form a white precipitate of calcium carbonate. This reaction causes the limewater to become cloudy or milky in appearance. It is a common test for the presence of carbon dioxide gas.
What is the test for C02?
Limewater. if carbon dioxide is present, limewater will turn milky/cloudy
What is the name of carbon dioxide gas test?
The test to detect the presence of carbon dioxide gas is called the limewater test. It involves passing the gas through limewater (a solution of calcium hydroxide) and observing a milky white precipitate forming if carbon dioxide is present.
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.
What is limewater and what is use for?
It is a test for carbon dioxide.
