Flame test lab answers
How are elements identified by using a flame test? A metal salt is a compound of a metal and a nonmetal. When dissolved in water, the metal and nonmetal atoms separate into charged particles called ions. As the metal ion is heated by the flame, the electrons gain energy and move to outer orbitals. Teacher Notes. This lab was developed by merging an old confirmation flame test lab with ideas from the original Mystical Fire lab created by educators Jesse Bernstein, Jeffrey Bracken, and Paul Price. They shared this lab at an Inquiry Based AP Chemistry Workshop in Miami, Florida on November 16, 2013 that they co-hosted.To carry out the flame tests, a small amount of the compound being tested will be held in a flame and the colour given off observed. This colour originates from the movement of electrons in the metal ion. When heated, the electrons gain energy, and are ‘excited’ into higher energy levels; however, the electrons occupying these levels is ...

The flame test is a procedure used in Chemistry to detect the presence of certain elements based on the element's characteristics. The test shows the identity of the substance being tested. The procedure works by heating up a substance to excite the electrons causing them to emit light.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. hobby lobby springfield il 1) Put on your goggles/apron and light your Bunsen burner, setting it to the hottest flame. 2) To perform the flame test, hold the atomizer about 10 cm to the side of the flame and give a quick spray directly into the hottest part of the flame.
