Question
1. Refer to Data Table A.2 and state the solutions that produce reactions similar to (a) Li State the elements in this experiment that belong to: (a) Group IA/1 (b) Ba 2. (b) Group IIA/2 An unknown solution gives a brief green flame test. The unknown gives a white precipitate with ammonium carbonate, ammonium phosphate, and ammonium sulfate. The halide test produces a purple color in the upper hexane layer. Identify (a) the alkali or alkaline earth element, and (b) the halide present in the unknown solution. 3. 4. An unknown solution gives a scarlet-red flame test. The unknown gives no reaction with ammonium carbonate, ammonium phosphate, and ammonium sulfate. The halide test produces an orange color in the upper hexane layer. Identify (a) the alkali or alkaline earth element, and (b) the halide present in the unknown solution. An unknown solution gives a brick-red flame test with flashes of yellow. The unknown gives a white precipitate with ammonium carbonate and ammonium phosphate, but no reaction with ammonium sulfate. The halide test produces no reaction in the upper hexane layer. Identify (a) the alkali or alkaline earth element, and (b) the halide present in the unknown solution. .
