Unformatted text preview: James Riddle Jr39592 Experiment 10 Determining the Ksp of Calcium Hydroxide Desai, K The first objective was to titrate a saturated calcium hydroxide solution with a standard HCl solution. The other two objectives were to determine the concentration of the hydroxide ion for the saturated calcium hydroxide solution and to calculate the Ksp of calcium hydroxide. (1) First, calcium hydroxide was mixed with distilled water to create a saturated solution. The solution was then filtered. 25.0 mL of this solution was then titrated with .050 M HCl recording the pH after each increment of HCl until the pH was around three. This process was performed two more times for a second and third trial. (2) The moles of hydroxide ion are calculated first by determining the moles of HCl. This was done by multiplying the amount of liters of HCl used to reach the equivalence point by the concentration of the HCl. The volume used in the calculations was taken from the data table. The moles of HCl are equal to HCl....
