What is the solid and gas produced in quicklime?
Quicklime, or calcium oxide, produces solid calcium hydroxide when mixed with water. The gas produced is typically carbon dioxide, as the quicklime reacts with carbon dioxide in the air to form calcium carbonate.
What type of reagent do you use for testing the presence of carbon dioxide. please list all of them...please..?
Bubble gas through limewater (saturated calcium hydroxide solution). The presence of carbon dioxide is indicated by the solution turning milky/cloudy. This is caused by the carbon dioxide and calcium hydroxide reacting to produce calcium carbonate which is insoluble, and is therefore seen as a white precipitate.
Why did the lime water change in reaction of acids lab?
In the reaction of acids lab, lime water (calcium hydroxide solution) changes due to the formation of calcium carbonate when carbon dioxide gas is produced by the acid reacting with a carbonate or bicarbonate. The reaction can be summarized as follows: when an acid is introduced, it reacts with the carbonate present, releasing carbon dioxide, which then reacts with calcium hydroxide in lime water to form the insoluble calcium carbonate. This results in a milky appearance, indicating the presence of carbon dioxide. The lime water's change reflects the acid-base reaction and the subsequent precipitation of calcium carbonate.
What is produced when limewater and carbon dioxide reacts?
When limewater (calcium hydroxide solution) reacts with carbon dioxide, it forms a white precipitate of calcium carbonate. This is a chemical reaction that is often used to test for the presence of carbon dioxide gas.
Does nitrogen turn limewater chalky?
No, nitrogen does not turn limewater chalky. Chalky precipitates in limewater are a result of carbon dioxide reacting with calcium hydroxide to form calcium carbonate. Nitrogen does not participate in this reaction.
How is slaked lime produced from limestone?
Heat it, the limestone (calcium carbonate) loses carbon dioxide to leave qucklime (calcium oxide). Add water to form slaked lime (calcium hydroxide).
How do you find out if what you breathe out is carbon dioxide?
you can try bubbling the carbon dioxide you breathe out into limewater aka calcium hydroxide solution. if the limewater tuns milky or cloudy, it confirms that the gas produced is carbon dioxide.
Explain why calcium hydroxide can be used in this way?
Calcium hydroxide is used to test for carbon dioxide because the product of the reaction, calcium carbonate, is insoluble, and easily visible.
What gas is produced when potassium hydroxide and calcium carbonate are mixed?
When potassium hydroxide and calcium carbonate are mixed, carbon dioxide gas is produced as a result of a double displacement reaction. The balanced chemical equation for this process is 2KOH + CaCO3 -> Ca(OH)2 + K2CO3.
What is the word equation for the making of concrete?
calcium hydroxide + carbon dioxide = calcium carbonate + water
What is the chemical that can absorb carbon dioxide?
Carbon dioxide is absorbed in calcium hydroxide and other hydroxides.
Why does lime water turn chalky when cardon dioxide is present?
The carbon dioxide forms a precipitate with the calcium hydroxide. (Lime water is just a solution of calcium hydroxide) This precipiate is what makes it look chalky
