Consider the compounds with the generic formula listed and their corresponding molar solubilities in pure water. Which compound has the smallest value of Ksp?

a. AC; molar solubility = 1.35 x 10^-4 M
b. AX2; molar solubility = 2.25 x 10^-4 M
c. A2X; molar solubility= 1.75 x 10^-4 M

Is it a?

1 answer

Why not simply calculate the solubililty of each.
