Problem: Calculate the molar solubility of AgI in a 1.0 M NH3 solution.

FREE Expert Solution

AgI (s) → Ag+ (aq) + I(aq)   Ksp = 8.3 x 10-17


Ksp=productsreactants=[Ag+][I-]

 Ag+ (aq) + 2NH3 (aq) →  [Ag(NH3)2]+      Kf = 1.7 x 107


Kf=productsreactants= [Ag(NH3)2 ][Ag+][NH3]2


Overall:

AgI (s) → Ag+ (aq) + I(aq)  

Ag+ (aq) + 2NH3 (aq) →  Ag(NH3)(aq)

_____________________________________

AgI (s)  + 2NH3 (aq)  I(aq)  + Ag(NH3)2 (aq)    K = Ksp(Kf)
