You add an excess of Ca(OH)2 to water maintained at a particular temperature, stir until the solution is saturated, filter, then determine the [OH-] in the solution by titration with acid. Titration of 25.0 mL of the calcium hydroxide solution to the endpoint requires 15.59 mL of 0.050 M HCl solution.
The molar quantity of OH- in the 25.0 mL of solution is:
0.780 mmol
What are the concentrations of Ca2+ and OH-?
