Why does exhaled air turn limewater chalky faster than inhaled water?
carbon dioxide turns lime water chalky. the more carbon dioxide, the faster the limewater turns chalky. Exhaled air contains carbon dioxide waste from the bodies organs, and that's why it contains more carbon dioxide than inhaled air.
Why does exhaled air turn limewater milky?
Cuz chuck Norris pised on it
Why does exhaled air turn limewater colour?
Exhaled air turns limewater milky because it contains carbon dioxide, which reacts with calcium hydroxide in the limewater to form calcium carbonate, a white precipitate. This reaction is a demonstration of the presence of carbon dioxide in exhaled air.
Does limewater absorb CO2?
Yes, limewater (calcium hydroxide solution) reacts with CO2 in the air to form insoluble calcium carbonate, causing the limewater to turn milky or cloudy. This reaction is often used as a test for the presence of CO2.
What can be observed when air is blown into limewater?
When air is blown into limewater, it turns milky white due to the formation of calcium carbonate. This happens because the carbon dioxide in the air reacts with the calcium hydroxide in limewater to form insoluble calcium carbonate, which gives the solution a milky appearance.
Why will limewater turn colourless when after bubbling through it for too long?
Limewater (calcium hydroxide solution) turns colorless after bubbling through it for too long because it reacts with carbon dioxide in the air to form calcium carbonate, which is insoluble and precipitates out of the solution. This process reduces the concentration of calcium hydroxide in the limewater and causes it to lose its milky appearance.
What will happen when you blow air through a test tube of limewater?
When you blow air through a test tube of limewater (a saturated solution of calcium hydroxide), the carbon dioxide (CO2) in your breath reacts with the calcium hydroxide to form calcium carbonate, which is insoluble in water. This reaction causes the limewater to turn milky or cloudy, indicating the presence of carbon dioxide. This phenomenon is often used as a simple test for CO2. Over time, the cloudiness may settle as the calcium carbonate precipitates out of the solution.
Why does limewater go misty when it is blown into?
to check if exhaled air has more carbon dioxide
Why is mineral oil added to the vial containing limewater?
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.
What happens to copper when mixed with limewater?
When copper is mixed with limewater, no immediate reaction occurs. Limewater is a solution of calcium hydroxide, which is not reactive with copper. However, if copper is exposed to air and moisture over time, it may develop a greenish layer of copper carbonate on its surface.
Why must limewater be stored in a sealed container?
Because over time the C02 in the air will react with the lime water (Calcium Hydroxide) to produce a white insoluble calcium carbonate precipitate (hence when you bubble C02 through it goes cloudy). The reaction is like so: Ca(OH)2 + CO2 → CaCO3 + H2O
