Problem
Two hypothetical salts are studied at 25∘C.
Salt P: Ksp=0.95
Salt Q: Ksp=1.3
Which prediction about their relative solubilities is most consistent with these data?
(a) P will dissolve more than Q because a smaller Ksp signals greater solubility.
(b) Both salts have nearly identical solubilities since any Ksp between 0.1 and 10 indicates sparing solubility.
(c) Both salts should be quite soluble, and Q is expected to dissolve slightly more than P.
(d) Q will dissolve completely while P begins to precipitate because Q’s Ksp is greater than 1.
