Suppose that you are performing a flame test with multiple solutions. First, you test a potassium compound, which appears violet. Then, you test a calcium compound, which should produce a brick red flame. However, you do not see the correct flame color. For each incorrect flame appearance, select the most likely error responsible and the necessary action to address it. Incorrect appearance 1. The frame appears weakly yellow, A. There is a sodium impurity somewhere. Compare to a known sodium compound to distinguish B. There is some of the previous metal left on the wire. Clean with acid and try again C. There is not enough solution on the wire. Dip it back in the solution and try again Incorrect appearance 2. The flame remains blue A. There is some of the previous metal left on the wire. Clean with acid and try again B. There is a sodium impurity somewhere Compare to a known sodium compound to distinguish C. There is not enough solution on the wire. Dip it back in the solution and try again Incorrect appearance 3. The flame appears violet A. There is not enough solution on the wire. Dip it back in the solution and try again B. There is some of the previous metal left on the wire. Clean with acid and try again C. There is a sodium impurity somewhere. Compare to a known sodium compound to distinguish.
