Q: What is calcination?
A: Calcination is a process that involves converting materials such as limestone or chalk into quicklime (calcium oxide) by heating them in a kiln at high temperatures.
Q: What is slaked lime?
A: Slaked lime is a less caustic form of lime, and it is formed by adding water to quicklime (calcium oxide) resulting in the formation of calcium hydroxide.
Q: What is the difference between quicklime and slaked lime?
A: Quicklime is the highly caustic form of lime, while slaked lime is a less caustic, but still strongly alkaline form of lime that is less dangerous.
