Calcium hydroxide is a strong base. Calcium hydroxide is only slightly soluble in water. But whatever dissolved in water is completely dissociated into its constituent ions, Ca2+ and OH- making it a strong base. The concentration of OH- ions is twice as the concentration of Ca2+. Ca(OH)2(aq) --> Ca2+ (aq) + 2OH- (aq) Pushpa Padmanabhan

Ca(OH)2, calcium hydroxide, is considered a strong base because it dissociates completely in water to produce hydroxide ions. This results in a high concentration of hydroxide ions in solution, leading to a high pH.

Because in solution it disassociates to almost 100% in it's constituent ions.

Ca(OH)2

to

Ca 2+

and, more importantly for a base

2OH -
