Calcium hydroxide is a base that does not dissolve very well in water. When saturated, a calcium hydroxide solution at 25°C contains 1,3 gram Ca(OH)2 per dm3 solution. The molar mass of Ca(OH)2 is 74,1 g×mol–1.
When the Ca(OH)2 dissolves, the following reaction represents the solubility equilibrium:
Ca(OH)2 (s) D Ca2+ (aq) + 2 OH– (aq)
Use this information above to find the value of Ksp for Ca(OH)2 at 25°C.
What is the pH of this saturated Ca(OH)2 solution?
