Ag+ forms complex ions with NH3 and S2O32- according to the following equilibria: Ag+(aq) + 2 NH3(aq) = [Ag(NH3)2]+(aq) K = 1.7 x 107 Ag+(aq) + 2 S2O32-(aq) = [Ag(S2O32-)2]3-(aq) K = 2.9 x 1013 Determine the value of K for the equilibrium: [Ag(S2O32-)2]3-(aq) + 2 NH3(aq) = [Ag(NH3)2]+(aq) + 2 S2O32-(aq) Using your K value as a guide, predict what would happen when 1 M NH3(aq) is added to a solution of [Ag(S2O32-)2]3-(aq). Explain your reasoning.

Review equation 16.10 and step B2. Ag+1(aq) and NH3(aq) will form a soluble complex ion. Use rule 3 of Water-Insoluble Salts in Appendix E to determine what would happen if Ag+1(aq) was combined with KOH instead of NH3. Write the net ionic equation with phase subscripts, where K+1 is a spectator ion which is cancelled out. Equation 16.10: Ag^+(aq) + Cl^-(aq) ⇄ AgCl(s) ⇅ 2NH3(aq) [Ag(NH3)2]^+(aq) Step B2: Silver Chloride equilibrium. To the clear solution from part B.1, add 5...
