What happens chemically when quick lime is added to water ?

 when quick lime is added to water formation of slaked lime takes place,Ca(OH)2.this is highly exothermic reaction.

 Thanks both of ya ;)

 CaO + H2O  ----------> Ca(OH)2

(quick lime )  ------> CaO

(slaked lime)  ------> Ca(OH)2

(water) ------> H2O

Calcium oxide reacts with water to produce slaked lime releasing larege amount of heat . It is an example of Combination Reaction .

Quick lime (calcium oxide, CaO) readily forms calcium hydroxide(slaked lime) as shown:

CaO   +   H2O      Ca(OH)2


Hope it helps.
