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
