In a titration experiment to determine the Ksp of Calcium Hydroxide, we titrated our prepared Ca(OH)2 solution with a standard hydrochloric acid solution. From the Initial pH, and the equivalence points of the titration curve and the second derivative curve, how would you calculate the [OH-] and the [ ca+2] from the averaged results of the titration curves and 2nd derivatives? there should be two calculations for each
