We are asked to calculate the Ksp of Ca(OH)2 when it is shaken with water to produce a saturated solution. This solution is filtered and a 60.00 mL sample and was titrated with HCl requiring 11.18 mL of 0.0978 M HCl to reach the endpoint. 


Step 1: First, we will get the number of moles of hydroxide. The reaction that happens during titration is:


Ca(OH)2 (aq)   +   2 HCl (aq)  →  CaCl2 (aq)    +  2 H2(l)    

A coefficient of two (2) is added to HCl and H2O to balance the equation.
