Question

what happens when calcium hydroxide reacts with water please give appropriate answer​

Answer 1

Answer:

When mixed with water, a small proportion of it dissolves, forming a solution known as limewater, the rest remaining as a suspension called milk of lime

Answer 2

Answer:Calcium hydroxide, also called slaked lime, Ca(OH), is obtained by the action of water on calcium oxide. When mixed with water, a small proportion of it dissolves, forming a solution known as limewater, the rest remaining as a suspension called milk of lime.

This then used in industries to make cement and other derivatives of calicium hydroxide

Explanation:

There is really not a chemical reaction for the very logical reason that Ca(OH)2 is already the result of a reaction with water from a calcium component.

CaO + 2H20 ==> lots of heat + Ca++ + 2 OH- + H2

After drying you have Ca(OH)2

And if you trow that powder in water you get :

Ca (OH)2 + H2O ==> Ca2+ + 2OH-
