Problem

Which salt precipitates first and what is the minimum concentration of Ag + necessary to cause this precipitation in a solution containing 7.5 mL of 0.025 M NaCl and 7.5 mL of 0.025 M Na3PO4?  

(Hint: dilution occurs)

Ksp(AgCl) = 1.8 x 10-10

Ksp(Na3PO4) = 1.3 x 10-20

a) AgCl              8.7 x 10  -7 M

b) Ag3PO4         2.3 x 10  -7 M

c) AgCl              1.4 x 10  -8 M

d) Ag3PO4         7.2 x 10  -8 M

e) None of these answers are correct
