A salt, #AB_3#, expresses an aqueous solubility of #0.0750*mol*L^-1# with respect to the given solubility? What is #K_"sp"# for this solute?
We examine the following equilibrium:
Since the solid cannot express a concentration, we write the following expression to represent the
As is usual in these problems, we raise each concentration to the power of the stoichiometric coefficient in the solubility expression, and thus we have the product
But we are given that
Are you happy with this?
