Student Handout for Flame test (Microsoft Word 38kB Aug2 09) Flame Tests. This page describes how to perform a flame test for a range of metal ions, and briefly discusses how the flame color arises. Flame tests are used to identify the presence of a relatively small number of metal ions in a compound. Not all metal ions give flame colors. For Group 1 compounds, flame tests are usually by far the easiest ...First, prepare your lab by placing the goggles over your eyes, connecting the bunsen burner to the gas, heating the bunsen burner with the lighter, and placing wooden sticks inside of the elements. Then, place one of the saturated sticks into the flame. Finally, observe the various colors that will appear based on the element that is tested.The most challenging activity in this lab was activity 3. This activity required the most precision. The easiest colors to observe during the flame test were that of copper chloride and lithium chloride. For potassium chloride there was a purple color close to the stick but the flame remained orange for the majority of the burn time.

Feb 21, 2020 · Moisten the wire with water. Dip the wire into the solid you're testing, making sue that a sample sticks to the wire. Place the wire in the flame and observe any change in the flame color. The colors observed during the flame test result from the excitement of the electrons caused by the increased temperature. 1. Get a Bunsen burner and a piece of rubber tubing for Bunsen burners. Check for any cracks or damage on the rubber tubing. Get a new piece of tubing if yours is damaged. Attach one end of the tubing to the gas source on the laboratory bench and the other end to the gas inlet on the Bunsen burner. 2.PROCEDURE: Using a scoopula, place a small amount of the metal salt solution into a clean petri dish. Add about an eye-droppers amount of methanol, into the petri dish (using and eyedropper). Allow the metal salt to dissolve for a couple seconds, then light the mixture with a match.
