A flame test is a procedure used to test qualitatively for the presence of certain metals in chemical compounds when the compound to be studied is excited by heating it in a flame, the metal ions will begin to emit light. Writing a flame test lab report is a serious assignment that implies practical research work, solid data analysis and some diligent writing as a rule, it takes nearly ten days to draw up a perfect lab report on any of high school and college topics.

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. Start studying flame test lab learn vocabulary, terms, and more with flashcards, games, and other study tools.
Flame test: red, green blue, violet activity—flame test worksheet 1 flame test worksheet by placing atoms of a metal into a heat source, electrons can be induced to absorb energy and in this lab we will prepare 2 m solutions of strontium chloride, copper ii chloride, and. A flame (from latin flamma) is the visible, gaseous part of a fireit is caused by a highly exothermic reaction taking place in a thin zone very hot flames are hot enough to have ionized gaseous components of sufficient density to be considered plasma. Flame tests flame tests are useful because gas excitations produce a signature line emission spectrum for an element in comparison, incandescence produces a continuous band of light with a peak dependent on the temperature of the hot object. This page describes how to do a flame test for a range of metal ions, and briefly describes how the flame colour 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 colours for group 1 compounds, flame tests.
Lab five flame test 1 flame tests objective in this experiment you will: • observe the flame colors emitted from selected ions • identify metallic ions by the color emitted during vaporization of the element • evaluate the usefulness of this method of metal identification. The flame test lab was an in-class lab where we tested chemicals in the flames to see the wide range of colors in the color spectrum the secondary purpose of the lab was to identify unknown compounds that we would test and then guess as to what they were. We offer clinical and industrial laboratory flame photometers from jenway and sherwood scientific. Lab 42 flame test lab background: 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.
The lab we did was a flame test we were supposed to subject various substances to flames, and see what would happen the color of the flame would determine the material i assumed the chemical makeup and the amount of subatomic particles generated different colors of the flames turn on the bunsen.

Jonathan ko honors chemistry mr barrientes oct 26th 2015 the effects of different metals on the color in the flame abstract: the lab on the effects of different metals on the color in the flame was a test to see if there would be any effect of the color of the flame if there were different kinds of metal ions in the fire. The flame test lab was an experiment designed to show how elements react when heated this lab attempted to prove that when electrons are excited and then calm, they emit a color specific to the element. Flame investment lab flame investment lab is imbued with the spirit and essence of liberal arts, where participants learn about value investing not only from the masters but also from a vibrant peer group.
