Would your calculated Ksp value be greater, less, or the same, if the following occurred, please explain your reasoning.
a. The CaSO4 was not saturated
b. You accurately measured 20.00 mL instead of 25.00 mL using a pipet
c. The CaSO4 solution contained 1.0 M NaCl (aq)
d. When the CaSO4 was being dissolved, solid, soluble CaCl2
e. The end point of the titration was 2 mL before the equivalence point

I don't know the pro you used so I don't know what;s going on in part b. Part d needs work.
okay what about the others?
Of course you could have typed the procedure you followed.
Part d still needs to be completed.
For a, if the CaSO4 is not saturated solution then both Ca^2+ and SO4^2- wil be less than they should be and Ksp (experimentsl value) will be smaller than the actual value.
c. In freshman courses the addition of NaCl will not significantly affect the Ksp value. In more advanced classes you learn it will.
d. Some words are missing at the end.
e. End point before means Ca and SO4 are too small and Ksp experimental value will be too small.
