A basic solution contains the iodide and phosphate ions that are to be separated via selective precipitation. The I– concentration, which is 8.90×10-5 M, is 10,000 times less than that of the PO43– ion at 0.890 M . A solution containing the silver(I) ion is slowly added. Answer the questions below.
Ksp of AgI is 8.30×10-17 and of Ag3PO4, 8.90×10-17.
A) Calculate the minimum Ag+ concentration required to cause precipitation of AgI.
B) Calculate the minimum Ag+ concentration required to cause precipitation of Ag3PO4.
