Question

ou are given four unlabeled bottles, each containing a clear liquid, and the following information: :In the 4 bottles Ag. H (ignore the dissociation of water as a source of H). K Pb2, Cro2 NO. SO4 and I are present. Each cation and anion are present in only one of the four bottles. The following salts are only sparingly soluble and form precipitates: . vo . Ag CrOs (red), Agl (yellow), PbCrOs (yellow), Pblb (yellow). Pbso4 (white) will be II Assume all other possible salts are soluble enough so that no precipitate detected 2018 .The following redox reaction is possible yellow solution->orange solution Tests were performed on this set of four unlabeled bottles as in this experiment and the following table was constructed: white 2 ppt yellow yellow 3 pptppt vellow red 4 pptppt Yellow soln -orange Fill in the boxes with the chemical formulas of the precipitates. Identify the cation and anion in each bottle: 1 Bottle # Cation
