Titration data for the determination of the common ion effect: Trial 2: Final Buret reading (ml)-33.30; Initial Buret reading (ml)- 29.50; Temperature (Celcius)- 25 Voume of HCl used: Trial 2- 3.80mL. Report in proper sigfigs. 1. Calculate the molar solubility (in mol/L) of OH- and Ca2+. 2. Determine the solubility of Ca(OH)2 in g/L. (MM of Ca(OH)2 = 74.096 g/mol). 3. Calculate the Ksp of Ca(OH)2. Make sure to include the effect of the common ion in the calculation.
The buret was filled with 0.100 M HCl solution. Then was transferred in a 25.0 mL of saturated calcium hydroxide solution (2g of calcium hydroxide per 100 ml of water) in two separate E-flasks. Then 2 drops of phenolphthalein was added to each flask
