1A: Consider these compounds: A. PbF2
B. Ni(CN)2
C. FeS
D. CaSO4
Complete the following statements by entering the letter(s) corresponding to the correct compound(s). (If more than one compound fits the description, include all the relevant compounds by writing your answer as a string of characters without punctuation, e. g, ABC.)
Without doing any calculations it is possible to determine that magnesium hydroxide is more soluble than , and magnesium hydroxide is less soluble than .
It is not possible to determine whether magnesium hydroxide is more or less soluble than by simply comparing Ksp values.
1B: 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. nickel(II) hydroxide
A. Fe(OH)2
2. silver chloride
B. PbS
C. AlPO4
D. MnS
Write the expression for K in terms of the solubility, s, for each salt, when dissolved in water.
nickel(II) hydroxide
silver chloride
Ksp=
Ksp=
Note: Multiply out any number and put it first in the Ksp expression. Combine all exponents for s.
