What of these will show that a gas is carbon dioxide?
The gas can be identified as carbon dioxide using a limewater test, where the gas is bubbled through limewater causing it to turn cloudy. Additionally, a carbon dioxide gas sensor can detect the presence of carbon dioxide in the air. Chemical tests such as reacting the gas with sodium hydroxide can also confirm the presence of carbon dioxide.
What is lime water an indicator for?
Limewater is an indicator for Carbon Dioxide
What substance is produced when lime water goes cloudy?
When lime water goes cloudy, it indicates the formation of calcium carbonate. This occurs as a result of a chemical reaction between calcium hydroxide in the lime water and carbon dioxide in the air, leading to the formation of the white precipitate.
How can you test for carbon dioxide in thermal decomposition reaction?
You can test for carbon dioxide in a thermal decomposition reaction by passing the gas produced through limewater. If carbon dioxide is present, the limewater will turn cloudy due to the formation of calcium carbonate. Alternatively, you can use pH indicator paper, which will turn from blue to green or yellow in the presence of carbon dioxide.
Describe a test for carbon dioxide?
One common test for carbon dioxide is the limewater test. In this test, carbon dioxide is bubbled through limewater, which will turn cloudy in the presence of carbon dioxide due to the formation of calcium carbonate precipitate. This cloudiness indicates the presence of carbon dioxide.
How do you do the test for carbon dioxide?
To test the presence of carbon dioxide bubble the gas into the lime water. Carbon dioxide reacts to form calcium carbonate which turns cloudy.
How do you test the chemical of carbon dioxide and what are the result?
Bubbling an unknown reactant gas of a chemical reaction through a bottle containing lime water causes the clear liquid to become cloudy as calcium carbonate is precipitated out. This is he classic test for the presence of Carbon Dioxide

What is lime water an indicator for?
Limewater is an indicator for Carbon Dioxide
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.

Carbon dioxide and lime water?
CaCO3 (s) + H2O(l) CaCO3 is a white solid that appears cloudy in solution Limewater is also used in the chemical test for carbon dioxide. The chemical test is if carbon dioxide is mixed with limewater it then clouds. If this happens then the gas will be carbon dioxide.
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 a carbon dioxide test?
A carbon dioxide test is a medical test that measures the levels of carbon dioxide in the blood. It is often used to evaluate the body's acid-base balance and respiratory function. Abnormal levels of carbon dioxide can indicate conditions such as respiratory failure, kidney disease, or metabolic disorders.
How do you prove that carbon dioxide is produced when carbon is burned?
Trap the gas produced and bubble through lime solution (aqueous calcium hydroxide), if a cloudy precipitate is produced from the initially clear solution this proves that carbon dioxide was evolved.Ca(OH)2 (aq) + CO2 (g) → CaCO3 (s) + H2O (l)
