When NaCl is added to a solution of AgNO3, a white precipitate of AgCl forms. If concentrated ammonia, NH3, is added to this precipitate, a clear colorless solution forms containing [Ag(NH3)2]+. KBr solution added to this colorless solution will cause pale yellow AgBr to precipitate. List the species, Cl-, NH3, or Br- in order of decreasing stability of the compounds or complexes that they can form with silver and explain your reasons.
