Unformatted text preview: Lauren Taranow lmt827 11-27-11 Unique: 51070 Discussion - Experiment 10: K sp of Calcium Hydroxide The purpose of this experiment was to use a standard HCl solution to titrate a saturated calcium hydroxide solution. The K sp of the calcium hydroxide solution was calculated from the molar concentrations of Ca 2+ and OH- ions, as well as the initial pH of the calcium hydroxide solution. The solubility of calcium hydroxide was then determined from the solubility product constant. In the experiment, 0.3004 grams calcium hydroxide was mixed with 100.0 mL of water to and filtered through a Buchner funnel to create three 25.0 mL amounts of saturated calcium hydroxide solution used in the three titration trials. 20mL 0.500M hydrochloric acid was mixed with 180.0mL water to produce 200mL 0.050M HCl solution, which was added to a burette to titrate against the saturated calcium hydroxide solution. This titration was unique from the titration performed in experiment 5 because in this case, a strong acid is added to added to a...
