What is the white precipitate formed when carbon dioxide is added to lime water?
The white precipitate formed when carbon dioxide is added to lime water is calcium carbonate. This reaction occurs because the carbon dioxide reacts with the calcium hydroxide in the lime water to form calcium carbonate, which is insoluble and appears as a white solid.
When solid calcium carbonate is heated what is form?
CaCO3 --> CaO + CO2 Heated Calcium Carbonate (limestone) forms Calcium Oxide (quicklime) and Carbon Dioxide
Is calcium hydroxide a solid or a liquid?
Calcium hydroxide is a solid compound at room temperature.
What happens when you mix calcium oxide with water and carbon dioxide?
Calcium oxide is a very good chemical 'absorber' of both water and carbondioxide: CaO + H2O --> Ca(OH)2 CaO + CO2 --> CaCO3 Both reactions are exothermic 'gas to solid phase' reacions
What is the difference between soda lime and lime soda?
Soda lime is a mixture of sodium hydroxide and calcium hydroxide used to absorb carbon dioxide. Lime soda is a solution of lime (calcium hydroxide) and soda (sodium carbonate), often used in water treatment to soften water by precipitating calcium and magnesium ions.
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.
How could the solid calcium hydroxide be used to test for carbon dioxide?
Calcium ydroxide is just another word for "Limewater". Limewater turns milky in the presence of Carbon Dioxide.
What solid is produced when reacting sulphur dioxide with calcium hydroxide?
CaSO3

Is calcium hydroxide a solid or a liquid?
Calcium hydroxide is a solid compound at room temperature.
What happen when carbon di oxide passed through lime water in excess?
When carbon dioxide is passed through lime water in excess, a white precipitate of calcium carbonate is formed. This is because carbon dioxide reacts with the calcium hydroxide in lime water to form calcium carbonate, which is insoluble and appears as a solid in the solution. This reaction is used as a test for the presence of carbon dioxide gas.
Carbon dioxide and lime water?
CaCO3 (s) + H2O(l) CaCO3 is a white solid that appears cloudy in solution Limewater is also used in the chemical test for carbon dioxide. The chemical test is if carbon dioxide is mixed with limewater it then clouds. If this happens then the gas will be carbon dioxide.
Reason why calcium hydroxide is used to detect carbon iv oxide while potassium hydroxide solution is not?
Both hydroxides will react with carbon dioxide to form their respective carbonates. Calcium carbonate is largely insoluble in water and so it will form a visible solid precipitate. Potassium carbonate is soluble in water, so there will be no visible change to the solution.
When Calcium carbonate is heated .?
It decomposes into calcium oxide and carbon dioxide...
Is CaCO3 considered a solid after being heated?
After heating at high temperature calcium carbonate is decomposed in calcium oxide (solid) and carbon dioxide (gas).
Solid calcium oxide is exposed to a stream of carbon dioxide gas?
A chemical reaction will occur, resulting in the formation of calcium carbonate and releasing heat. This reaction is known as calcium oxide reacting with carbon dioxide to form calcium carbonate.
