The hydroxide ion concentration, [OH-], in each of your trials can be calculated from the concentration of the hydrochloric acid, 0.050 M HCl, and the volume of both the HCl and Ca(OH)2 used in the titration. According to the net ionic equation (calcium hydroxide, Ca(OH)2 (s), in water) determine the ratio of moles of calcium ion, Ca2+, to moles of hydroxide ion, OH-, in the solution of calcium hydroxide, Ca(OH)2. Using this ratio, determine the molarity of calcium ion in...
