Determining Ksp of Calcium Hydroxide Purpose: To find Ksp of Calcium Hydroxide Procedure: 1.Obtain and wear goggles 2. Measure exactly 15 mL of the filtered solution into a 50 mL beaker. Record the precise volume pf Ca(OH)2 solution. 3. Position the pH sensor in the Ca(OH)2 solution 4. Add the pH probe and check the pH, It should be above 7. 5. Check the initial volume of the buret. Slowly add the .05 M HCL until the pH reaches 7. Record the volume needed to reach a pH of 7. Data Ca(OH)2 11.1 mL Ca(OH)2 13.7 mL Ca(OH)2 15.2 mL Ca(OH)2 12.3 mL
