lime water turns milky in the presence of CO2 Limewater (a solution of Calcium hydroxide) - when carbon dioxide is blown through the solution, a precipitate of Calcium carbonate is produced. The solution is said to turn "milky" or "cloudy". Bromothymol blue (pH range 2.4 to 4.6) (red in colour) is added to distilled water, which turns it yellow. Carbon dioxide turns the resulting yellow solution green.
Two solutions that can be used to test for carbon dioxide are limewater (calcium hydroxide solution) and bromothymol blue indicator. Limewater turns milky when carbon dioxide is present, indicating the formation of calcium carbonate. Bromothymol blue changes color from blue to yellow in the presence of carbon dioxide.

In the test tube shown what is the produced by the snail that is used by the plant?
carbon dioxide
What happens when carbon dioxide is treated with limewater?
When carbon dioxide is treated with limewater (calcium hydroxide solution), a white precipitate of calcium carbonate forms. This is a chemical reaction that is commonly used to test for the presence of carbon dioxide gas.
Purpose of lime water with marble chip?
Lime water with marble chips is used in a laboratory setting to test for the presence of carbon dioxide. When carbon dioxide is bubbled through lime water, it forms a white precipitate of calcium carbonate, indicating the presence of the gas. This test can be used to verify the gas as a byproduct of a chemical reaction or in environmental monitoring.
What are the uses of carbon dioxide dioxide?
The following r the uses of carbon dioxide:- 1) carbon dioxide is used to produce aerated cold beverages. 2) carbon dioxide is used to produce dry ice. 3) carbon dioxide is used to extinguish fires. 4) carbon dioxide is used to make washing soda. 5) carbon dioxide is used to produce sodium bicarb(baking powder). 6) plants make their own food by using carbon dioxide.
What test is used to assess a mineral based on its reaction with a substance that may or may not produce carbon dioxide bubbles?
Carbon dioxide and water are produced when acids react with carbonate compounds. Therefore, if an acid reacts with a particular mineral and produces carbon dioxide, that mineral contains carbonate compounds.
Which liquid is used to test for carbon dioxide?
Carbon dioxide levels are tested through the blood
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.
In the test tube shown what is the produced by the snail that is used by the plant?
carbon dioxide
What substance used to detect the presence of carbon dioxide?
Test for Carbon Dioxide: Bubble unknown gas in lime water. Limewater should go milky if Carbon dioxide is present. Test for water: Add anhydrous copper sulphate crystals (white in colour) to unknown solution. If solution goes a brilliant light blue colour, water is present as the hydrous copper sulphate crystals were formed. Did this help?
Why can't potassium hydroxide be used to test for carbon dioxide?
Potassium hydroxide reacts with carbon dioxide to form potassium carbonate, which is an alkaline salt and can lead to false positive results when testing for carbon dioxide. This can interfere with the accuracy of the test. Sodium hydroxide is typically used instead, as it does not form a similar reaction with carbon dioxide.
What gas turns lime water milky white?
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.
Carbon dioxide and lime water?
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 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.
How could the solid calcium hydroxide be used to test for carbon dioxide?
Calcium ydroxide is just another word for "Limewater". Limewater turns milky in the presence of Carbon Dioxide.
What happens when carbon dioxide is treated with limewater?
When carbon dioxide is treated with limewater (calcium hydroxide solution), a white precipitate of calcium carbonate forms. This is a chemical reaction that is commonly used to test for the presence of carbon dioxide gas.
Which test is used to distinguish between carbon dioxide and carbon monoxide?
Gases can be passes into lime water.Only CO2 turns it into milky
Which test is used to assess a mineral based on its reaction with a substance that may or may not produce carbon dioxide bubbles?
