Which is more basic calcium carbonate or calcium oxide?
Calcium oxide (CaO) is more basic than calcium carbonate (CaCO3) because it has a higher pH level and readily reacts with water to form a strong alkaline solution. Calcium carbonate is less basic as it is a common form of limestone and chalk and does not exhibit strong basic properties.
When carbon IV oxide is passed into lime water for a long time the product formed is?
When carbon dioxide is passed into lime water for a long time, calcium carbonate forms. Calcium carbonate precipitates out of the solution, turning the lime water cloudy or milky.
Why does not wall imidiately acquire white colour when a coating of slaked lime is applied?
As slaked lime is of calcium hydro oxide it takes time. when heat react with calcium hydro oxide the water of calcium get evaporated it become quick lime (calcium carbonate). as the water evaporated the carbon dioxide get a chance to react with calcium carbonate and forms white colour.....

What is the word equation for calcium oxide and water?
In most industrial processes calcium carbonate and water is the product of the combination of calcium hydroxide and carbon dioxide.Calcium hydroxide + carbon dioxide → calcium carbonate + water
What is inside calcium carbonate?
CaCO3 + H2CO3(aq) -> CaCO3 + H2CO3(aq) There is nothing to drive any sort of reaction at conditions near STP. At elevated temperatures such as would be found in a cement kiln, the calcium carbonate would decompose to calcium oxide and carbon dioxide while the carbonic acid would have long since evaporated to give water vapor and carbon dioxide.
Can calcium oxide be used to neutralise water polluted with acid rain?
No, you need Calcium Carbonate not Calcium Oxide to neutralize the acid.
What mixed with calcium carbonate gives off ammonia?
When calcium carbonate is mixed with ammonium sulfate, it can give off ammonia gas. This reaction occurs because calcium carbonate will decompose upon heating to form calcium oxide, water vapor, and carbon dioxide, while ammonium sulfate will decompose to release ammonia gas.
How does the limestone cycle work?
Starts off as Calcium Carbonate , when heated the calcium carbonate becomes Calcium Oxide + Carbon Dioxide, the Calcium Oxide then reacts with water to produce Calcium Hydroxide and then when more water is added then filtered it becomes Calcium Hydroxide Solution, C02 is then added to form Calcium Carbonate again [:
How can you convert CaCO3 to Ca?
You can convert CaCO3 (calcium carbonate) to Ca (calcium) by heating it at a high temperature in the presence of a reducing agent, such as carbon. This process, known as calcination, will decompose the calcium carbonate, releasing carbon dioxide and leaving behind calcium oxide. The calcium oxide can then be reacted with water to form calcium hydroxide, which can further be processed to obtain pure calcium.

What is the difference between calcium carbonate and calcium oxide?
Calcium oxide is a compound of calcium and oxygen and has the formula CaO. It is very basic (alkaline) and will react with water to form calcium hydroxide, Ca(OH)2 which is a strong base. Calcium oxide is commonly called lime or quicklime.Calcium carbonate is a compound of calcium, carbon, and oxygen with the formula CaCO3. It is mildly basic and will not react with water nor is it water soluble. It is commonly called calcite, limestone, or marble.
What reactions can take place with calcium carbonate and limeatone?
When calcium carbonate reacts with an acid, it produces carbon dioxide gas, water, and a calcium salt. When calcium carbonate reacts with heat, it decomposes into calcium oxide (quicklime) and carbon dioxide gas. Lime stone, which is primarily composed of calcium carbonate, can undergo similar reactions.

When you heat copper carbonate why does it turn lime water milkey?
Heating copper carbonate decomposes it to form copper oxide, carbon dioxide, and water vapor. The carbon dioxide produced reacts with the lime water (calcium hydroxide solution) to form calcium carbonate, which is insoluble and gives the milky appearance. This is a simple test for the presence of carbon dioxide.
What is the word equation for calcium oxide and water?

What is a lime?
a type of citrus fruit and calcium oxide that is greenLime is Calcium Carbonate (usually upto 96% plus other metallic elements) in it's natural form, when you burn it, it becomes calcium oxide, generally speaking for building you then add it to water making calcium hydroxide then it resets back to calcium carbonate... thus the lime cycle.
