Quicklime, also known as calcium oxide, when mixed with water undergoes an exothermic reaction, releasing heat. However, it does not produce fire. The reaction can generate enough heat to cause burns or ignite flammable materials nearby due to the high temperatures reached.
Quicklime was left exposed before being transported to allow it to fully react with water and carbon dioxide, forming calcium hydroxide. This process helps stabilize the quicklime and prevents the release of heat during transportation.
No, hydrated lime (calcium hydroxide) is produced when quicklime (calcium oxide) reacts with water. Once this reaction occurs, the chemical properties change, and it cannot revert back to quicklime without undergoing a separate process involving heat (such as calcination).
Quicklime is created from limestone through a process called calcination. The chemical equation for this process is: CaCO3 (limestone) -> CaO (quicklime) + CO2 (carbon dioxide). It involves heating limestone to high temperatures, around 900-1000°C, to drive off the carbon dioxide and produce quicklime.
When calcium oxide (quicklime) dissolves in water, it undergoes an exothermic reaction which may produce a hissing sound due to the rapid release of heat and steam. The hissing sound is a result of the quick reaction of the lime with water to form calcium hydroxide.
adding water to quick lime produces slaked lime.

When quicklime (calcium oxide) is added to water, it undergoes a chemical reaction called slaking to form calcium hydroxide. This reaction releases a significant amount of heat due to the exothermic nature of the reaction. The resulting calcium hydroxide solution is highly alkaline.

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).

Water is distilled by evaporating it, usually by adding heat and bringing it to boil
Limestone to quicklime: Calcium carbonate ---heat---> calcium oxide (QUICKLIME) + carbon dioxide Chemical formula: CaCO3 ---heat---> CaO + CO2 Quicklime to slaked lime: Calcium oxide (QUICKLIME) + water ---> calcium hydroxide (SLAKED LIME) Chemical formula: CaO + H20 ---> Ca(OH)2
The limstone cycle: 1. Limstone (CaCO3) - Heat limestone to produce quicklime 2. Quicklime (CaO) - Add a few drops of water to produce slaked lime 3. Slake lime (Ca(OH)2(s)) - Add excess water to produce Limewater 4. Limewater (Ca(OH)3(aq) ) - Bubble CO2 gas into limewater to produce limestone This is called a cycle because it happens again and again...
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 [:
