Academics

Given the following equilibria and their constants: AgCl(s) ? Ag+(aq) + Cl-(aq); Ksp = 1.6 x 10-10 Ag+(aq) + NH3(aq) ? Ag(NH3)+(aq); K1 = 2.1 x 103 Ag(NH3)+(aq) + NH3(aq) ? Ag(NH3)2+(aq); K2 = 8.2 x 103 (a) Determine the equilibrium constants for the following equilibria: (i) Ag+(aq) + 2NH3(aq) ? Ag(NH3)2+(aq); Kf = ? (ii) AgCl(s) + 2NH3(aq) ? Ag(NH3)2+(aq) + Cl-(aq); Kc = ? (b) Calculate the solubility (in mol/L) of silver chloride in 2.0 M NH3 solution. How many grams of AgCl will dissolve in 500. mL of 2.0 M NH3?
