(A) Calculate the solubility in moles/liter (M) for Ba3(PO4)2 in pure water (Ksp = 6.0 x 10^-39.) (Ignore any acid/base behavior)
(B) Determine the equilibrium expression that enables calculation of the solubility (S) in moles/liter (M) for Ba3(PO4)2 in 1.0 x 10^-3 M BaCl2 and calculate the solubility. (Ignore any acid/base behavior).
(C) Determine the equilibrium expression that enables calculation of the solubility (S) in moles/liter (M) for Ba3(PO4)2 in 2.5 x 10^-2 M Na3PO4. Also, calculate the solubility.
