The titration is at endpoint which means that all of the base is neutralized by the acid.
Ca(OH)2(aq) + 2HCl(aq) ⟶ CaCl2(aq) + 2H2O(l)
1 mole Ca(OH)2 : 2 mole HCl
Recall:
Calculate moles Ca(OH)2:
= 9.15 x 10-4 mol Ca(OH)2
A sample of solid calcium hydroxide, Ca(OH)2, is allowed to stand in water until a saturated solution is formed. A titration of 75.00 mL of this solution with 5.00 × 10−2 M HCl requires 36.6 mL of the acid to reach the end point.
Ca(OH)2(aq) + 2HCl(aq) ⟶ CaCl2(aq) + 2H2O(l)
