Another test for CO2 gas is the lime water test. When carbon dioxide gas is bubbled through lime water, it will turn milky due to the formation of calcium carbonate.
When carbon dioxide is passed through lime water it goes cloudy.
One way to identify the gas is to pass it through lime water (calcium hydroxide solution). If the gas turns the lime water milky white, it indicates the presence of carbon dioxide (CO2). Another method is to ignite the gas. If it produces a popping sound or a small explosion, it is likely hydrogen (H2).
Carbon dioxide gas is collected when a uninflated balloon is placed around a test tube of yeast. This is because the yeast produces carbon dioxide gas as a byproduct of the fermentation process.
A respirometer test can be used to measure the CO2 production in respiration. This test involves placing a living organism in a sealed chamber and measuring the changes in gas levels to determine the rate of oxygen consumption and CO2 production. The respirometer can help researchers understand the metabolic activity and energy expenditure of the organism.
Carbon dioxide or CO2.
When carbon dioxide is passed through lime water it goes cloudy.
The gas yielded from a chamical reaction should be allowed to pass through clean lime water. If the gas is CO2, it turns lime water milky by formation of CaCO3. This is the confirmatory test for CO2 gas

Bubbling the gas into limewater is the classic test for CO2. Limewater is a saturated solution of Ca(OH)2. When CO2 is dissolved it reacts to produce insoluble CaCO3 and the solution turns cloudy. Ca(OH)2(aq) + CO2(aq) --> CaCO3(s) + H2O(l) :)

Carbon dioxide (CO2) gas rises in the atmosphere.

oxygen and co2
Put the gas (CO2) in lime water. If the lime water changes colour, then it means that there is carbon dioxide in the gas depending on how fast the lime water changes colour
Carbon dioxide (CO2) is an inorganic gas.
CO2 gas is colorless, and it is covalently bonded.
Carbon dioxide gas turns lime water milky white by forming insoluble calcium carbonate when added to it. This reaction is commonly used as a test for the presence of carbon dioxide.
