Limewater will turn milky white when carbon dioxide is added to it due to the formation of calcium carbonate.
Mineral oil is added to the vial containing limewater to prevent the absorption of carbon dioxide from the air. This helps to maintain the limewater solution saturated with calcium hydroxide, which is necessary for its intended use in chemical experiments or tests.
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.
to test for carbon dioxide is already dissolved in limewater, after this shake up the test tube, is it be that carbon dioxide is present then 2 things will happen: 1) the limewater will turn cloudy as CO2 is a precipatate is this solution 2) the limewater will begin to show efferevescence now we know gas is present If these 2 things happen then there is an extremely high chance that CO2 is present I hope this answers any questions about the test for C02 i hope this help remember dont skip school
Lime water turns milky when carbon dioxide is added to it.Lime water also turns into Calcium carbonate (Limestone) solution
These is because, it contain's dissolved carbon dioxide (CO2) as the anion CO32-; carbon dioxide is added to improve the taste and for raising the acidity.
If there is oxygen in limewater, it would stay clear. Limewater (calcium hydroxide solution) is typically used to detect the presence of carbon dioxide. If carbon dioxide is present, it forms a white precipitate of calcium carbonate, turning the limewater cloudy or milky.

the colour of the indicator will increase

When dilute hydrochloric acid is added to sodium carbonate solution, it produces bubbles of carbon dioxide gas. This can be tested by passing the gas through limewater, which will turn milky if carbon dioxide is present. Additionally, the gas can be identified using a flame test, where carbon dioxide does not support combustion.
When vinegar is added to marble chips (calcium carbonate), carbon dioxide gas is formed. This can be identified by observing bubbles forming in the solution during the reaction. The presence of carbon dioxide can also be confirmed by passing the gas through limewater, which will turn milky if carbon dioxide is present.

what is product when zinc added to carbon dioxide?
Marble is formed from limestone, primarily calcium carbonate. Vinegar is acetic acid. The reaction between the two produces water, carbon dioxide, and calcium acetate. We know this from balancing the equation. See the related question.
Carbon dioxide
Copper Carbonate (CuCO3) is heated up so that a decomposition reaction occurs, with the products being Copper (II) Oxide (CuO) and Carbon Dioxide (CO2). The chemical formula is: CuCO3 --> CuO + CO2. If proper apparatus is set up, the carbon dioxide should travel down a tube into limewater (Ca(OH)2), which react to create solid calcium carbonate (CaCO3, also known as chalk) and water (H2O). The calcium carbonate is the reason why the 'limewater' turns milky. This proves that there is CO2 present. The chemical formula for this is: Ca(OH)2 + CO2 --> CaCO3 + H2O.
