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).

Is filtering a reversible or irreversible change?
reversible
Is mixing oil and water a reversible or irreversible change?
reversible
Is tea a reversible change or non-reversible change?
It is not a reversible change. During boiling some components are extracted with hot water from the crushed dried leaves. It is impossible to restore the original leaves.
Is a puddle evaporating a reversible or irreversible change?
Yes, evaporation is the changing of matter from a liquid to a gas. You can reverse this process through condensation which is the change from a gas to a liquid.
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).
Why is slaking of lime is necessary?
- to obtain calcium oxide - to obtain calcium hydroxide
How many times the volume of fat lime increases compared to volume of quick lime on slaking?
2-2.5 times.
Why is slaking of lime regarded as a chemical change?
because new substance is formed in chemical composition & hence they cannot be reversed.
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.
How do you pronounce slaking?
"(Slaking)".
At what level do you evolves to slaking?
u dont slaking doesnt evolve. but a vigoroth evolves into slaking at lvl 32
What rock turns into plaster when heated?
Limestone is quarried, broken up and heated to specific controlled temps. This resulting "quicklime" is then 'slaked' ( a special soaking process) in water to make a dry hydrate that is bagged and sold to the public. When the dry lime is again mixed with water into a plaster, it will cure- because of the AIR- on the walls and the reabsorption of air/CO2, turns the powder back into limestone again. Cement is the opposite- adding water stars the curing process immediately. Lime plaster needs time, and thin application, for the air to cure it back into limestone. Limestone is NOT calcined at high heat-- the temp. is kept under 1800 deg to reduce the busted up stone to a 'quick' lime. Slaking does not take 6 months to 10 years. A controlled quick lime process takes only enough time for the added water to turn the lime back into a dry powder, which is now called Hydrated lime- sold in 50# bags- this is what most Americans buy to mix as plaster or mortar, or farm use. Quick lime is too dangerous to safely mix for the DIYer, so it is harder to find and buy. Quick lime IS sold as lump lime in bags, and the slaking process occurs then, under controlled conditions by experienced mixers. Hot lime gives off steam and heat in an exothermic event when the water and quick lime meet; this is where moisture in your eyes, nose, or skin causes burning during the slaking process. SOAKING the powdered hydrated lime in water for months and years produces a better, creamier product to work with. ( Slaking happens only once) This lime is very drying and can be caustic to skin, but is not dangerous, will not give off heat/steam; thousands of natural builders are using it daily.
Where to find a slaking in SoulSilver?
You cannot find Slaking in Soul Silver. To get one, you must capture a Slakoth by headbutting trees on route 25. Then evolve it into a Slaking. Or you could get a friend to trade you a slaking or you could transfer a Slaking from a Gen 3 game into Soul Silver via Pal Park.
What is the national pokedex number for Slaking?
Slaking is #289 in the national pokedex, and it is a Normal type Pokemon.
What is slake lime?
Quicklime is calcium oxide - CaO and slaked lime is calcium hydroxide - Ca(OH)2. CaCO3--------------CaO + CO2 This reaction occur at high temperature; mixing calcium oxide with water, the hydroxide is obtained.
Where to find a slaking?
you dont a slaking just by catching it,slakoth may be swarning in eterna forest thats the only way slakoth to vigoroth at lv 18 and vigoroth to slaking at lv 36
What level does vigoroth evolve into slaking?
Slaking doesn't evolve as it is already at it's final stage of evolution. Slakoth evolves into Vigoroth at level 18 and then Vigoroth into Slaking at level 36.
