The solubility product for an insoluble salt with the formula M₂X₃ is written as ________, where s is the molar solubility.

Question

Quizplus · Accepted Answer

The solubility product expression for an insoluble salt with the formula M2X3 is Ksp = [M2+][X3]3. Since the molar solubility of the salt is s, the concentrations of M2+ and X3- in a saturated solution are both equal to s. Substituting these values into the Ksp expression, we get Ksp = s2(3s)3 = 27s5.
