Question

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

Answer 1

Calcium oxide reacts with water to form calcium hydroxide, also called slaked lime.

Here are the equations for this reaction:

Calcium oxide + water $\to$ calcium hydroxide

$CaO+H_{2}O\to Ca(OH{)}_2$

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.
