Each of the following tests was run on a different unknown solution. State which ion is indicated by the observation. Assume no interfering ions are present to complicate the test for each ion. a) Addition of 6 M NaOH and Al to the solution produces a gas which turns moistened red litmus paper blue. b) Addition of 6 M nitric acid makes a yellow solution turn orange. c) Addition of any strong acid produces an effervescence. d) Addition of silver nitrate produces a white precipitate. e) Addition of barium chloride produces a white precipitate. f) Addition of 6 M nitric acid plus 0.5 M ammonium molybdate produces a yellow precipitate 2. You are given an unknown which contains one or more of the 7 ions listed in this Experiment. You conduct the following tests, each on separate portions of the unknown. After each test, list the conclusion(s) drawn from that test. After the tests, tabulate the 7 possible ions as present, absent, or in doubt. a) Addition of 6M nitric acid causes no effect. b) Adding nitric acid and silver nitrate causes no effect. c) Adding nitric acid and 1 M barium chloride produces a white precipitate. d) Nitric acid plus ammonium molybdate produces a yellow precipitate. lons present lons absent lons in doubt
