Although solubility and color are key factors in identifying the anion present in a salt, anions can also be grouped by common chemical characteristics, specifically, reaction with strong acids and with precipitating agents. In the first part of this analysis, students will perform tests on the anions being studied. Three classification tests, Reaction with Concentrated Sulfuric the of a Gas, Reaction with Silver with Barium used to group these is to remember that some of the anions will not exhibit positive result with one or more of these classification tests. Negative results are just as important as positive ones Upon the completion of the classification tests a nfirmatory test will be performed on each anion. In order for the student to use sound judgment in the analysis unknown anion sample they must understand a positive confirmatory resul Although individual confirmation will be done on of the anions the halides are confirmed with the same test. Each halide will give a each Chloride yellow, bromide unique color upon the completion of the test: iodide -purple. orange and Once the classification and confirmatory tests are completed on the known salts student will be assigned a sample of an unknown anion. Students will be expected to perform the classification tests and then choose the appropriate confirmatory test to perform. A. Classification Test I-Reaction of Anions with Concentrated Sulfuric Acid in the Production of a Gas Chloride, bromide, iodide, and carbonate anions all produce a gas in reaction with COLD concentrated sulfuric acid, (H.Sol). A chloride salt will react to form the halide, H2SO4(aq) 4 (aq)
