The Benettis want your company to identify the compound in ... More experiments can be done with machines to find the exact wavelengths of light for every element. For more information on these offerings, select a testing option. When the electron moves back down to a lower energy state, it emits light and produce a flame color.1 Sometimes there is more than one flame color because an electron might go from the 4s orbital then go to the 2p orbital which means two colors will be produced. The flame test is used to visually determine the identity of an unknown metal or metalloid ion based on the characteristic color the salt turns the flame of a Bunsen burner. Flame tests and chemical tests are used to detect and identify ions in samples. 4. 2017/2018. View Lab Report - Lab Report.pdf from CHEMISTRY 101 at Memorial High School.

After obtaining the color of each of the known metal ion solutions, repeat the flame test for a single metal unknown and an unknown mixture of two metal ions. When metal salts (ionic compounds) are heated in a Bunsen burner flame, the metal gives off a characteristic color. While it's a useful qualitative analysis test—and a lot of fun to perform—it can't be used to identify all metals because not all metal ions yield flame colors. Hypothesis If the element (independent variable) is placed in the fire (controlled variable), then the From the flame color, identify the metal ions in your unknowns and record your results on your report form. tests with each cation to discover each ion’s characteristic behavior. Meanwhile, for Group V is different for each ions, it also can be done by flame test for group V. To identify anions are different for each ion, but before done further test, the sample should be heated with sodium carbonate to remove all heavy metals. Lab: Flame Tests Note for Teachers : Showing the NOVA film about fireworks (titled Fireworks!) Our Lady of Fatima University. If one can tell if a planet has oxygen on it based on its bright line spectra, research could be done to tell if people can live on the planet or not.
