Ksp Calculated from the Saturated Ca(OH)₂ solution Use the pH to calculate [OH] in the solution: 14-2=2 OH = 10² - 10/ Complete the following ICE table: Ca(OH)₂ (s)- Initial Change Equilibrium Ca²+ (aq) 6.005 Use the equilibrium concentrations to calculate Kspi Ksp = (005) (₁01)² = 5x10- % enor - 15.5x 10-6- 5.5×100 @ 7 + 2 OH* (aq) 0.01 In this lab we used two different determinations of Ksp. Did you find that one of the two methods was more accurate than the other? Propose a possible explanation for your results. Ksp = C₂(OH)₂ = 5.5×106 Choose your more accurate Ksp value, calculate the percent error in your Ksp and discuss possible reasons your value may differ from the accepted value: P5.3
