Problem

Two hypothetical salts are studied at

25^{\circ}\text{C}

. \nSalt P:

K_{sp}=0.95

\nSalt Q:

K_{sp}=1.3

\nWhich prediction about their relative solubilities is most consistent with these data? a) P will dissolve more than Q because a smaller

K_{sp}

signals greater solubility. b) Both salts have nearly identical solubilities since any

K_{sp}

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

K_{sp}

is greater than 1.
