Write the equilibrium expression showing the dissociation of Ca(OH)2 in water. (Omit states-of-matter from your answer. )

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

Explanation:

Calcium hydroxide is sparingly soluble in water. It dissociates to give the following:

The net ionic equation :

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

Since, H2O doesn't affect the overall reaction, therefore;

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