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.
When carbon dioxide is bubbled through lime water (a solution of calcium hydroxide), it forms a white precipitate of calcium carbonate. This reaction is commonly used as a test for the presence of carbon dioxide. The equation for the reaction is: CO2 + Ca(OH)2 -> CaCO3 + H2O.

What does CO2 and lime water make?
When carbon dioxide reacts with lime water (calcium hydroxide solution), it forms a white precipitate of calcium carbonate. This reaction is commonly used as a test for the presence of carbon dioxide gas.
Which colour does the lime water change to when put in oxygen?
Lime water turns milky or cloudy when exposed to oxygen. This is due to the formation of calcium carbonate as the lime water reacts with carbon dioxide in the air.
What is limewater element or compound?
Limewater is a saturated solution of calcium hydroxide (Ca(OH)2) in water. It is a compound made up of calcium, oxygen, and hydrogen atoms. Lime water turns milky when carbon dioxide is passed through it, due to the formation of calcium carbonate.
When you make lime water why do you filter the calcium hydroxide?
Filtering the calcium hydroxide in lime water removes any undissolved particles or impurities present in the solution. This helps ensure that the lime water is clear and free of solid debris, which could affect the accuracy of experiments or desired applications where a clear solution is needed.
What are the word equations for processes that release or store carbon doixide?
The word equation for the process that releases carbon dioxide through respiration is glucose + oxygen -> carbon dioxide + water + energy. The word equation for the process that stores carbon dioxide through photosynthesis is carbon dioxide + water + sunlight -> glucose + oxygen.
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 happens when carbon di oxide passes through lime water?
Carbon dioxide turns lime water milky.
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 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
