An unknown hydroxide of the formula X(OH)2 is only slightly soluble in water. A scientist is curious as to what hydroxide this is. So, she takes this hydroxide and dissolves enough of it in pure water to make a saturated solution. She then takes 25.00 mL of the saturated solution and titrates it with 0.000100 M HCl. She notes that it takes 2.58 mL of HCl to fully neutralize the saturated solution.  1. Determine the Ksp of the hydroxide. (concentration of X(OH)2  is 1.032 x 10-5 M, pH = 9.31, molar solubility should be 1.032 x 10-5 M)
