Which of the following statements is held true about the common-ion effect on the equilibrium of solubility of salt ?
(you may choose more than one answer)
Adding common-ion to the solution containing dissolved salt cause the solubility equilibrium shifts to the formation of undissolved salt
Adding common-ion to the solution containing dissolved salt cause the numerical value of Ksp of corresponding salt changes
Solubility of salt in solution containing common-ion is greater than that of pure water.

The Ksp expression for a saturated solution of Ca3(PO4)2 is
Ksp = [Ca2+][PO43-]
Ksp = [3Ca2+][2PO43-]
Ksp = [Ca2+]3[PO43-]2
Ksp = [3Ca2+]3[2PO43-]2
