What of reaction is the reaction of quick lime with water?

Calcium oxide reacts with water to form calcium hydroxide, also called slaked lime. Here are the equations for this reaction: Calcium oxide + water → calcium hydroxide. C a O + H 2 O → C a (O H) 2. A lot of heat is produced in the reaction, which may even cause the water to boil.Hence it is a combination reaction as well as exothermic reaction.
