13. Calculate the value for the equilibrium constant, Ksp for the following reaction.
Ca(OH)2 (s) Ca+2 (aq) + 2 OH- ⇆
(aq) assume that a 20.00 mL sample of saturated Ca(OH)2 was titrated with a 0.050 M standard HCl solution to the equivalence point. Assume that 8.1 mL of standard HCl was needed to get to the equivalence point.
(I am having trouble with this one. Let me know if there is additional information needed)
Answer
ie Ksp = 4*10^-6

ALT CHEM 125 Name Determining the Ksp of Calcium Hydroxide Calcium hydroxide is an ionie solid that is sparingly soluble in water. A saturated, aqueous, solution of Ca(OH), is represented in equation form as shown below. Ca(OH)2 (5) --- Ca' (aq) + 2OH(aq) The solubility product expression describes, in mathematical terms, the equilibrium that is established between the solid substance and its dissolved ions in an aqueous system. The equilibrium expression for calcium hydroxide is shown below. Kp - [Ca][OHT...
