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. In today’s lab, flame tests will be used to see how the valence electrons of an atom are excited by the energy of the flame, and then release that energy by giving off a characteristic color of light. (5)Dip your wire into a metal salt either the nitrate or chloride and place the wire onto the tip of the blue flame. Chemistry The Flame Test Name OBJECTIVE: To observe the emission spectra of several metals. A flame test is an analytical procedure used in chemistry to detect the presence of certain elements, primarily metal ions, based on each element's characteristic emission spectrum. Academic year. Share. Flame Tests Last updated; Save as PDF Page ID 3673; The Origin of Flame Colors; Contributors and Attributions; This page describes how to perform a flame test for a range of metal ions, and briefly discusses how the flame color arises. When the compound to be studied is excited by heating it in a flame, the metal ions will begin to emit light. We can examine the properties of an unknown substance and compare those properties with those of known substances in order to determine a match. Students will record the dominant flame color observed. The flame test is a qualitative test used in chemistry to help determine the identity or possible identity of a metal or metalloid ion found in an ionic compound. Your name.

This flame test lab is always a favorite of mine, and a much loved lab by all of my students. Our flame test was in lab class, where the main aim was to tested different solid metals in the flame in order to observe the wide variety of colors those chemicals also sometimes compounds (by mixing them) they produced, the second one was to identify unknown metals based on their flame color . Embed. Calcium Chloride 2. The different colors of flames are produced by electrons moving from a higher to a lower energy level and are useful in identifying an element. Based on this information, please make notes for use in your lab report. Flame Test Lab Activity Key Note: If chloride compounds are not available, metal nitrate compounds may be substituted.

(down loaded file) The student will conduct flame tests on a number of unknown salt compounds. Do you think that potassium could be detected visually in the presence of sodium by heating this mixture in a flame? The student will then use this data to identify an unknown metal ion by using a flame test. Related documents. Pre-Lab Discussion: The normal electron configuration of atoms or ions of an element is known as the “ground state.” In this most stable energy state, all electrons are in the lowest energy levels available. Safety: Always use good safety techniques. In this lab you will be given six unknown samples of metal salt, and you must determine which salt is which.
