In our lab experiment, we filtered CaCl2 and CaOH2 solutions that we prepared the previous week and transferred both of the filtrates using a 25 ml pipette into two Erlenmeyer flasks. We then prepared the standard HCl by pipetting 100 ml of HCl to prepare 250 ml of 0.04M HCl from the 0.1 M HCl solution that we initially had. We pipetted 100 ml of HCl into a 250 ml volumetric flask and diluted it to the mark. The buret was filled with the prepared HCl and both the CaCl2 and CaOH2 were titrated until a yellow endpoint was reached, this titration was repeated three times for each solution.
The result for Ksp of CaCl2=6.881 x 10-6
Ksp for CaOH2= 7.11 x 10-6
Q. Do you expect the two Ksp values to be consistent or inconsistent? Explain why.
