1. Make a detailed flow chart for this experiment on the backside of this paper. 2. For each of the following experiments, use your flow chart to determine which of the three Group III cations are: DEFINITELY PRESENT, DEFINITELY ABSENT, & POSSIBLY PRESENT. Ammonium carbonate solution is added to the unknown solution which may contain only Group III cations. A precipitate forms which dissolves completely when treated with acetic acid. After treatment with ammonium acetate and potassium chromate, no precipitate forms. DEFINITELY PRESENT DEFINITELY ABSENT POSSIBLY PRESENT 3. NaOH is added to a fresh sample of the unknown in an evaporating dish which may contain only Group III cations. A piece of red litmus is moistened and attached to the underside of a watchglass. The dish is heated. Blue spots appear on the litmus, but no odor of ammonia is detected. DEFINITELY PRESENT DEFINITELY ABSENT POSSIBLY PRESENT 4. (NH4)2CO3 solution is added to the unknown solution which may contain only Group III cations. No precipitate forms. DEFINITELY PRESENT DEFINITELY ABSENT POSSIBLY PRESENT 5.
