The test involves introducing a sample of the element or compound to a hot, non-luminous flame, and observing Each substance. Reason. Flame Test Lab Purpose The purpose of the flame test lab is to identify a set of flame-test color standards for selected metal ions, and to relate the colors of a flame test to the behavior of excited electrons in a metal ion. Ethanol (IDA) – Flammable may be harmful by inhalation, ingestion or skin absorption may act as an irritant. This flame test lab is always a favorite of mine, and a much loved lab by all of my students. III. The Flame Test Student Worksheet. Instrumental methods of analysis are faster, and more accurate and more sensitive than simple chemical tests. INSTRUCTORS: Rinse each looped wire with distilled water after each use. (5)Dip your wire into a metal salt either the nitrate or chloride and place the wire onto the tip of the blue flame. Comments. Closure strategies will occur next day (due to time) with a discussion and a short quiz. Chemistry The Flame Test Name OBJECTIVE: To observe the emission spectra of several metals. There are directions to be found by clicking here. Your instructor will dip a looped wire into one of the solutions supplied, and then hold it in the Bunsen burner flame. Students will record the dominant flame color observed. Page 2/5.
