4. An alkaline earth hydroxide, M(OH)2, was taken to lab for analysis.

The unknown powder was poured into a flask and swirled in room temperature DI water until a saturated solution formed.

This solution was then slowly filtered to remove the undissolved solid hydroxide. 28.5 mL of this saturated solution was titrated with 0.163 M HCl (aq). Endpoint required 24.90 mL of the HCl (aq) solution.

Calculate the Ksp for this alkaline earth hydroxide.
