In a titration with HCl and Ca(OH)2 where a 10 mL sample o Ca(OH)2 (aq) is prepared, if some of the Ca(OH)2 was transferred into the 10 mL sample, how would the volume of HCl used in the titration be affected? How would this affect the calculated Ksp (for Ca(OH)2)? How would this affect the calculted molar solubility of Ca(OH)2
