Calcium oxide is a drying agent---it is used to wick away any water that wants to condense into the reaction (because ammonia is extremely hydroscopic).

Calcium oxide is added in the Haber process for ammonia production as it acts as a desiccant to absorb any moisture present in the reactants, which can lower the efficiency of the process. By removing moisture, the equilibrium shift in the reaction favors the production of more ammonia, thus increasing the overall yield.

It's an exothermic reaction that produces calcium hydroxide.


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.

When you add water to calcium oxide what does it give?

Calcium Hydroxide is the product when Calcium Oxide is reacted with water. It is an exothermic reaction liberating heat. This process is called slaking. CaO + H2O -----> Ca(OH)2.


What would a farmer do if his soil was to acidic?

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).


What is slake lime?

Slaked lime, also known as calcium hydroxide, is a dry powder formed by adding water to quicklime (calcium oxide). It is commonly used in construction, agriculture, and water treatment as a pH stabilizer and for its disinfectant properties.


Which is more basic calcium carbonate or 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.


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 happens when you add calcium oxide and sulphuric acid?

When calcium oxide (CaO) is added to sulfuric acid (H2SO4), they undergo a chemical reaction to form calcium sulfate (CaSO4) and water (H2O). This reaction is an example of a neutralization reaction, where an acid and a base react to produce a salt and water.
