How many times the volume of fat lime increases compared to volume of quick lime on slaking?
2-2.5 times.
Explain why sublimation is regarded as a physical change but the slaking of lime is considered as a chemical change?
- Sublimation don't change the molecule; solid iodine or sublimated iodine are iodine. - Slaking of lime transform the calcium oxide in calcium hydroxide. A chemical change occur.
Why is slaking of lime regarded as a chemical change?
Slaking of lime is considered a chemical change because it involves a chemical reaction. When water is added to quicklime (calcium oxide), it reacts exothermically to form slaked lime (calcium hydroxide), releasing heat. The chemical composition of the substance changes during this process, demonstrating a chemical change.
Is slaking of lime reversible?
Yes but it is not a single step reversal. You start off with Limestone (CaCO3) you heat this and drive off Carbon dioxide (CO2) making Quicklime (CaO). You then slake the Quicklime by adding water (H2O) to make Slaked Lime (Ca(OH)2). The Slaked lime will slowly turn back into limestone by reacting with the Carbon Dioxide (CO2) in the air - it is Carbonated - to make Limestone (CaCO3).
How is slake lime made?
adding water to quick lime produces slaked lime.
How do you pronounce slaking?
"(Slaking)".
What does it mean by slaking?
Slaking refers to the process of adding water to a dry material, typically quicklime (calcium oxide), to produce calcium hydroxide (slaked lime). This exothermic reaction generates heat and results in a hydrated substance that can be used in various applications, such as in construction, agriculture, and water treatment. In a broader sense, slaking can also describe the act of quenching thirst or alleviating a need.
Why is quick lime called quicklime?
Quicklime is called so because of its property to react quickly with water, producing heat and forming calcium hydroxide. This reaction is known as slaking and results in a rapid increase in temperature, hence the term "quick" lime.
What is meant by slaking of lime?
It is the process of converting CaO to Ca(OH)2 by adding the CaO into water. The reaction is: CaO+H2O ---> Ca(OH)2 This reaction is highly exothermic and releases large amount of heat (63.7 kJoules for 1 mol of CaO used).
What happens when you mix water and lime?
When water is mixed with lime (calcium oxide), a chemical reaction occurs to produce calcium hydroxide and release heat. This process is known as slaking and is used to create a hydrated lime paste that is commonly used in construction and as a mortar. The resulting mixture can also be used to create lime mortar for masonry work.
How do you think slaked lime is manufactured from limestone?
Slaked lime is manufactured from limestone by heating limestone (CaCO3) to high temperatures to produce quicklime (CaO), then adding water to the quicklime to create calcium hydroxide, also known as slaked lime (Ca(OH)2). This process is known as slaking.
What kind of climate is necessary to grow a lime tree?
The kind of climate that is necessary to grow a lime tree is moderate to sunny climates though there are a few varieties such as the persian lime tree that can withstand a cooler climate.
