25.00 mL of a saturated Ca(OH)2 sample requires 22.50 mL of 0.0250 M HCl to neutralize it. Calculate the value for Ksp of Ca(OH)2 from this data. Given the equilibrium equation:         Ca(OH)2 (s) ↔ Ca2+ (aq) + 2OH– (aq) 1) Write the Ksp expression?    2) Use titration data to determine moles of OH¯ in the 25.0 mL sample (Remember, every one H+ neutralizes one OH¯.)        3) Use moles of OH¯ and sample volume to determine [OH¯]:      4) Determine [Ca2+]:      5) Calculate the Ksp for Ca(OH)2
