For each of the salts on the left, match the salts on the right that can be compared directly, using Ksp values, to estimate solubilities.

(If more than one salt on the right can be directly compared, include all the relevant salts by writing your answer as a string of characters without punctuation, e. g, ABC.)

1. lead fluoride (answer here )
2. aluminum hydroxide (answer here )
A. Mg(OH)2
B. BaF2
C. Ag3PO4
D. AgI

Write the expression for K in terms of the solubility, s, for each salt, when dissolved in water.

lead fluoride

aluminum hydroxide

Ksp =

Ksp =

Note: Multiply out any number and put it first in the Ksp expression. Combine all exponents for s.
