WebMay 28, 2024 · 0. If a pure metal is heated up in a flame, we see it giving the flame a characteristic color, e.g. N a burns yellow. If a salt, e.g. N a C l or N a X 2 S O X 4, is heated up, resulting color to a greater degree still is that of the pure metal. Although the color does change depending on the anion, this effect is usually not much pronounced. WebClick the Flame w/Cobalt button and record your observations in the same table. Drag the K+ test tube to the metal stand to exchange it with the Na+. Perform a flame test on K+ with and without cobalt glass. Record your observations in the data table. For the other four ions, perform a regular flame test only. Do not use the cobalt glass.
