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.$)$

fill in the blank $1$

$1.$ silver carbonate A$.$ AgCN

fill in the blank $2$

$2.$ calcium sulfate B$.$ AgI

C$.$ Zn$($OH$)2$

D$.$ Al$($OH$)3$

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

silver carbonate

calcium sulfate

Ksp $=$

Ksp $=$

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