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. calcium sulfide
2. calcium fluoride
A. BaSO3
B. Cu(OH)2
C. PbBr2
D. Zn(OH)2
Write the expression for K in terms of the solubility, s, for each salt, when dissolved in water.
calcium sulfide
Ksp =
calcium fluoride
Ksp =
Note: Multiply out any number and put it first in the Ksp expression. Combine all exponents for s.
