Title: Solubility
Post by: Maxwell on November 29, 2009, 08:19:49 PM

Calculate the solubility of solid Ca₃(PO₄)₂
 (Ksp = 1.3E-32)  in a .20 M Na₃PO₄ solution.


 I am confused on how to find solubility of solutions. I understand how to get the solubility of a single compound using Ksp=products  but I dont know how to find solutions. can anyone help me?

Look in your text for "common ion effect."
