In-Lab Question 7. Describe the location of each cation in the separation scheme and the confirmatory test used to confirm the presence of that ion. (Choose the correct description from the right-hand column for each ion.) Ag Ba2 Fe3 A. This ion does not precipitate with HCl, ammonia or H2SO4. B. This ion does not precipitate with HCl but will form a precipitate when ammonia is added. The precipitate re-dissolves when acid is added and forms a red solution in the presence of NaSCN. C. This ion forms a precipitate with HCl. The precipitate is soluble when ammonia is added and forms a red solution in the presence of NaSCN. D. This ion does not form a precipitate when HCl or ammonia is added. It will form a white precipitate in the presence of H2SO4. E. This ion does not precipitate with HCl but will form a precipitate when ammonia is added. The precipitate is red in color. F. This ion forms a precipitate with HCl. The precipitate re-dissolves when base is added and re-precipitates when acid is added.
