What gas does lime water change into?
When limewater goes cloudy it means carbon dioxide is present!
If you collect gas from a dead animal and bubble it through lime water the lime water turns cloudy what is the gas?
The gas collected from the dead animal and bubbled through lime water is likely carbon dioxide (CO2). This gas reacts with the lime water (calcium hydroxide) to form calcium carbonate, which is insoluble and appears as a cloudy white precipitate.
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.
What is test for carbon dioxide gas gas?
When carbon dioxide is passed through lime water it goes cloudy.
What is the test for co2 gas?
When carbon dioxide is passed through lime water it goes cloudy.
Why is lime water used as an indicator?
Lime water (calcium hydroxide) turns milky/cloudy when exposed to carbon dioxide due to the formation of calcium carbonate, which is insoluble. This property makes it a useful indicator for the presence of carbon dioxide in a substance or a gas.
How do you know that the air breathed out contains carbon dioxide gas?
You can test it with the Lime Water test. If there is carbon dioxide in your breath then the Lime Water should turn cloudy.
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 dioxide gas is passed through lime water?
It turns cloudy (or milky). Lime water is calcium hydrogen carbonate dissolved in water. When it comes into contact with carbon dioxide, they react together to make calcium carbonate (chalk), which is white and less soluble in water. So the fine white precipitate that forms makes the solution turn cloudy.
What is lime water an indicator for?
Limewater is an indicator for Carbon Dioxide
What chemical test could be used to confirm that the gas prodced in a chemical reaction is carbon dioxide?
The gas yielded from a chamical reaction should be allowed to pass through clean lime water. If the gas is CO2, it turns lime water milky by formation of CaCO3. This is the confirmatory test for CO2 gas
What happens to lime-water when you mix it with hydrogen and add a burning splint?
When lime-water is mixed with hydrogen and a burning splint is introduced, the mixture will produce a squeaky pop sound. This indicates the presence of hydrogen gas, as it reacts with oxygen in the air to create a small explosion. Lime-water itself does not react with hydrogen gas in this scenario.
