Hello everyone,

I did an experiment where I measured the solubility product constant, Ksp, of an ionic solid in water at 20 C, but my result was apparently slightly off because my result was a Ksp for a temperature more like 28 C. I do not recall having made any mistakes throughout the procedures. So I was wondering if anyone knew about any possible sources of error for having obtained a ksp value larger than what it should be?

The concentration of the dissolved ionic species, a base, was determined by titration.

Thank you so much in advance!

1. What's the difference? Can it be attribuited to limited accuracy of titration? Experimental error?

2. Have you accounted for ionic strength?
