What does CO2 and lime water make?
When carbon dioxide reacts with lime water (calcium hydroxide solution), it forms a white precipitate of calcium carbonate. This reaction is commonly used as a test for the presence of carbon dioxide gas.
Which colour does the lime water change to when put in oxygen?
Lime water turns milky or cloudy when exposed to oxygen. This is due to the formation of calcium carbonate as the lime water reacts with carbon dioxide in the air.
What is limewater element or compound?
Limewater is a solution made of Calcium Hydroxide and water. Calcium Hydroxide is found in things like oyster shells and bird eggs. There are many uses including food preparation, creating paint and topical medicines.
When you make lime water why do you filter the calcium hydroxide?
The limewater is filtered so that the undissolved particles of calcium hydroxide do not make the limewater solution cloudy even before it is used to test for carbon dioxide gas. By filtering it, the limewater solution is made clear and colorless, which makes it easier to notice it becoming cloudier when carbon dioxide gas is bubbled through it.
When methane is burned in a lime kiln why are the wast gages carbon dioxide and nitrogen?
When methane is burned in a lime kiln, the waste gases are carbon dioxide and nitrogen because methane (CH4) reacts with oxygen (O2) to produce carbon dioxide (CO2) and water vapor (H2O) during combustion. Nitrogen is also present in the air and is not directly involved in the combustion process, so it remains as a waste gas in the form of nitrogen (N2).
What is lime water an indicator for?
Limewater is an indicator for Carbon Dioxide
How would you test or carbon dioxide?
add lime water to the air if the lime water turns cloudy then carbon dioxide is present
How could we confirm that the gas generated was in fact Carbon dioxide?
Test it with lime water. If the lime water goes milky you have carbon dioxide.
What is the effect carbon dioxide in lime water?
Lime water turns milky when carbon dioxide is added to it.Lime water also turns into Calcium carbonate (Limestone) solution
What reacts with lime water forming a precipitate?
Carbon dioxide reacts with lime water (calcium hydroxide solution) forming calcium carbonate as a white precipitate.
Why does lime water absorb carbon dioxide?
ime water can be used to detect the presence of carbon dioxide because lime water reacts with carbon dioxide to produce a precipitate of calcium carbonate:Ca(OH)2 (aq) + CO2 (g) → CaCO3 (s) + H2O (l) no, lime water doesn't produce carbon dioxide, it just detects it.
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.
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 is the difference between soda lime and lime water?
Soda lime removes carbon dioxide from breathing gases, as in submarines for example, and thus prevent carbon dioxide poisoning. Lime water has a number of uses. It can detect the presence of Carbon Dioxide. It can be used in food products, corn tortillas for example. It is used to make sugar from sugar beet. It is used in seawater aquariums.
What happens when carbon di oxide passes through lime water?
Carbon dioxide turns lime water milky.
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.
What color does lime water change to when carbon dioxide is bubbled in?
Lime water changes from clear to milky/cloudy when carbon dioxide is bubbled in, indicating the formation of calcium carbonate.
