The document discusses the solubility of silver iodide (AgI) in the presence of ammonia. It provides the relevant equilibrium constants for the dissociation of AgI into Ag+ and I- ions (Ksp = 1.5 x 10^-16) and the formation of the Ag(NH3)2+ complex from Ag+ and NH3 (Kf = 1.6 x 10^7). It asks to write the net ionic equation for the increased solubility of AgI in ammonia and calculate the overall equilibrium constant by combining the individual constants.
