Calcium oxide slaking reaction
Webchemical reaction, so calcium hydroxide contains 75.7% CaO and 24.3% H 2O. The process of adding water to calcium oxide to produce calcium hydroxide is referred to as hydration process or lime slaking. The hydration of CaO, commercially referred to as quick lime, is an exothermic process releasing a great quantity of heat.
