It is a test for carbon dioxide.
limewater
The limewater test can differentiate between carbon dioxide and nitrogen. When carbon dioxide is bubbled through limewater, it turns milky due to the formation of calcium carbonate. Nitrogen will not have this effect on limewater.
Limewater, which is a solution of calcium hydroxide in water, is generally considered non-toxic. However, ingesting large amounts of limewater can lead to stomach discomfort and potential irritations. It is important to use limewater in recommended amounts and consult a healthcare professional if ingested in large quantities.
limewater.
Oxygen does not have a direct effect on limewater. Limewater is a solution of calcium hydroxide, and when exposed to carbon dioxide, it forms calcium carbonate, turning the limewater milky. Oxygen does not directly interact with the limewater in this chemical reaction.
Limewater fizzes when blown into through a straw.
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.
When carbon dioxide gas is passed through limewater, a white precipitate of calcium carbonate forms, causing the limewater to turn milky.
we can use limewater
If a gas is present in limewater, such as carbon dioxide, it will react with the limewater to form a white precipitate of calcium carbonate. This reaction causes the limewater to become cloudy or milky in appearance. It is a common test for the presence of carbon dioxide gas.
Limewater get milky at the presence of carbon dioxide dissolved in it.
