Question

A basic solution contains the iodide and phosphate ions that are to be separated via selective precipitation.
The I concentration, which is 9.20×10-5 M, is 10,000 times less than that of the PO43– ion at 0.920 .
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. mol/l

 

Calculate the minimum Ag+ concentration required to cause precipitation of Ag3PO4. mol/l
