When calcium oxide reacts with water to form calcium hydroxide, heat is released while the pH immediately reaches 12–13 and further increases over the next 30 min [27].

What is the difference between lime and quicklime?

The key difference between quicklime and hydrated lime is that the quicklime (or burnt lime) contains calcium oxide whereas the hydrated lime (slaked lime) contains calcium hydroxide. The major source for both quicklime and hydrated lime is the limestone. Therefore, like limestone, these compounds are also alkaline.
