A basic solution contains the iodide and phosphate ions that are to be separated via selective precipitation. The I– concentration, which is 7.80×10-5 M, is 10,000 times less than that of the PO43– ion at 0.780 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. Calculate the minimum Ag+ concentration required to cause precipitation of AgI. Calculate the minimum Ag+ concentration required to cause precipitation of Ag3PO4. I got the first part correct being 1.064x10^-12. the second part i got wrong, being 4.774x10^-14
