$CaO+ H_{2} O = Ca (OH)_{2}$

Answer 2

CaO + H2O -------------->Ca(OH)2

When quicklime is added to water it forms slakedlime. It is also called limewater .

The student will notice that slakedlime gets precitated at the bottom of the beaker .

The reation will be exothermic and it is also a combination reaction .
