Carbon Dioxide because,
The carbon dioxide reacts with the dissolved calcium compound to form calcium carbonate that is insoluble. This makes the newly formed substance precipitate out of solution making the lime water cloudy.
So yeah that's the answer:)
Limewater is a saturated solution of calcium hydroxide. When CO2 gas is bubbled into limewater it forms calcium carbonate, which is insoluble, and turns the limewater cloudy.
Oxygen or hydrogen are not very soluble in water, and they don't hydrolyze or form OH- ions that will shift the equilibrium. Therefore, O2 or H2 won't cause limewater to turn cloudy.

What is the effect carbon dioxide in lime water?
Lime water turns milky when carbon dioxide is added to it.Lime water also turns into Calcium carbonate (Limestone) solution
Why does lime water absorb carbon dioxide?
ime water can be used to detect the presence of carbon dioxide because lime water reacts with carbon dioxide to produce a precipitate of calcium carbonate:Ca(OH)2 (aq) + CO2 (g) → CaCO3 (s) + H2O (l) no, lime water doesn't produce carbon dioxide, it just detects it.
What gas do you test using lime water?
You can test for carbon dioxide gas using lime water. When carbon dioxide is blown into lime water, it turns cloudy due to the formation of calcium carbonate.
What color does lime water change to when carbon dioxide is bubbled in?
Lime water changes from clear to milky/cloudy when carbon dioxide is bubbled in, indicating the formation of calcium carbonate.
What gas identified by bubbling it through lime water?
Carbon dioxide gas can be identified by bubbling it through lime water. When carbon dioxide passes through lime water, it causes the lime water to turn milky due to the formation of calcium carbonate as a precipitate.
What is lime water an indicator for?
Lime water is an indicator for the presence of carbon dioxide gas. When lime water reacts with carbon dioxide, it forms a cloudy white precipitate of calcium carbonate.
How would you test or carbon dioxide?
add lime water to the air if the lime water turns cloudy then carbon dioxide is present
How could we confirm that the gas generated was in fact Carbon dioxide?
Test it with lime water. If the lime water goes milky you have carbon dioxide.
What is the effect carbon dioxide in lime water?
Lime water turns milky when carbon dioxide is added to it.Lime water also turns into Calcium carbonate (Limestone) solution
What reacts with lime water forming a precipitate?
Carbon dioxide reacts with lime water (calcium hydroxide solution) forming calcium carbonate as a white precipitate.
Why does lime water absorb carbon dioxide?
ime water can be used to detect the presence of carbon dioxide because lime water reacts with carbon dioxide to produce a precipitate of calcium carbonate:Ca(OH)2 (aq) + CO2 (g) → CaCO3 (s) + H2O (l) no, lime water doesn't produce carbon dioxide, it just detects it.
What gas do you test using lime water?
You can test for carbon dioxide gas using lime water. When carbon dioxide is blown into lime water, it turns cloudy due to the formation of calcium carbonate.
When you mix hydrochloric acid to calcium carbonate and transfer the gas to mix with lime water what is the lime water testing for?
The lime water is testing for the presence of carbon dioxide gas. When hydrochloric acid reacts with calcium carbonate, carbon dioxide gas is produced. This gas is then passed through the lime water, which will turn milky/cloudy if carbon dioxide is present.
What is the difference between soda lime and lime water?
Soda lime is a mixture of calcium hydroxide (lime) and sodium hydroxide used to remove carbon dioxide from closed environments, while lime water is a solution of calcium hydroxide in water used to test for the presence of carbon dioxide because it turns milky. Soda lime is used for absorbing carbon dioxide, while lime water is used for detecting carbon dioxide.
What happens when carbon di oxide passes through lime water?
Carbon dioxide turns lime water milky.
What chemical do you use to identify carbon dioxide?
Lime water (calcium hydroxide) is commonly used to identify carbon dioxide gas. When bubbled through lime water, carbon dioxide forms a white precipitate of calcium carbonate. This reaction is often used as a test for the presence of carbon dioxide.
What is a test to show that a gas is carbon dioxide?
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
