How is quick lime made?
Limestone, calcium carbonate, is heated until it glows. It will give off carbon dioxide and change into calcium oxide. Calcium oxide is called quicklime because it hisses and swells up when a drop of water is added to it, just as if it was alive. "Quick" used to be used to indicate that something was living, so in this case it would be alive-lime, or quicklime.
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
Function of lime water?
It is to test for the presence of carbon dioxide. If carbon dioxide is present,it will turn chalky however if carbon dioxide is absent,lime water will remain colourless.
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.
How do you text for carbon dioxide?
lime water (calcium hydroxide) turns milky when carbon dioxide is present
Why is carbon dioxide produced in the lime kiln?
In a lime kiln calcium carbonate is heated to form quick lime and carbon dioxide. CaCO3 -> CaO + CO2
What is the word equation for the endothermic reaction which occurs in lime kiln?
Calcium carbonate + heat= Calcium oxide + carbon dioxide is the word equation for the endothermic reaction which occurs in lime kiln.
When was Lime Kiln Middle School created?
Lime Kiln Middle School was created in 1999.
When methane is burned in a lime kiln why are the wast gages carbon dioxide and nitrogen?
the oxygen in the air combines with the methane making carbon dioxide and leaving un reacted nitrogen from the air.
Give two reactions which produce carbon dioxide in the lime kiln?
One reaction is calcium carbonate is calcium oxide plus carbon dioxide. Another reaction is carbon plus oxygen which equals carbon dioxide.
What occurs in a lime kiln?
A lime kiln is a kiln used to produce quicklime by the calcination of limestone (calcium carbonate). The chemical equation for this reaction is:CaCO3 + heat → CaO + CO2 This reaction takes place at 900°C (at which temperature the partial pressure of CO2 is 1 atmosphere), but a temperature around 1000°C (at which temperature the partial pressure of CO2 is 3.8 atmospheres) is usually used to make the reaction proceed quickly. Excessive temperature is avoided because it produces unreactive, "dead-burned" lime.
What reacts with lime water forming a precipitate?
Carbon dioxide
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 gas turns lime water milky white?
carbon dioxide CO2
