Suppose the K_a values for the hypothetical acids HX, HY, and HZ are 9.5 × 10^5, 7.6 × 10^4, and 1.2 × 10^2, respectively. Assuming that “A” is a cation that produces a slightly soluble salt with all three acids, which of the following salts

would have its solubility most affected (compared with its solubility

in pure water) when it is dissolved in a 0.10 M solution

of HCl?

a. AX

b. AY

c. AZ

d. The solubility of all the salts would be affected by the same amount.

e. There is not enough information given in the problem to determine the answer.
