question

An equilibrium solution of the complex ion Ag(NH_3)_2^+ contains 0.30 M of NH_4^+ and 0.15 M of the actual ^+complex ion. To obtain a concentration of Ag^+ equal to 1.0 × 10^-6 M, what must the pH of this solution be?K_dissof Ag(NH_3)_2^+ = 6.0 × 10^-8, K_b of NH_3 = 1.8 × 10^-5 and K_W = 1 × 10^-14.
