Formation of Calcium Hydroxide

CaO + H2O → Ca(OH)2

Ikhtisar

Calcium oxide (quicklime) reacts exothermically with water to form calcium hydroxide (slaked lime). This reaction generates considerable heat and can cause water to boil. It is one of the oldest known chemical reactions, used in construction for millennia.
