Flame test pre-lab (pre-ap chemistry) introduction the electrons in an atom occupy different energy levels when all of the electrons are at the lowest possible. Flame test: red, green blue, violet activity—flame test worksheet 1 flame test worksheet write a lab report with the following information included. Flame test: going further chemistry topics always wear safety goggles when handling chemicals in the lab always be aware of an open flame do not reach over. Kelsey strouse lab partner: avery martin 12/17/12 flame tests abstract: in this flame test experiment, seven different known solutions and three different unknown.
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. With the flame tests chemistry laboratory kit, students observe the characteristic color of light emitted by metallic salts when placed in a flame this basic lab activity is ideal for physical science and introductory chemistry classes add a splash of color to your flame in this kit, students. Then determine the identity of 2 unknown ions using a flame test and the emission line spectra from the known ions your task: in your lab notebook decide what data you will need to collect in order to answer the research question. The purpose of flame tests is to identify unknown metals and metalloid ionssafety is crucial in any flame test wear protective goggles, have a water source nearby and beware of ingesting or inhaling harmful odors.
Flame tests provide a good teaching tool for chemistry students learning about emission spectra unlike more sophisticated spectrographic equipment, a flame test requires only a gas burner, a hydrochloric acid solution and nichrome wire to hold the sample. Flame test: aim: to determine which part of the salt is responsible for the characteristics in the flame hypothesis: if we introduce a metal salt in the blue flame of the bunsen burner, then the colour given off by the flame is due to the metal part of the salt. Click to enlarge this graphic looks at the colour of various metal and metalloid ions that occur during flame tests most people probably remember doing this experiment in school chemistry lessons, if not with the full range of ions shown here, but for the uninitiated a brief explanation of the origin of the colours follows. Lab: flame tests discussion: when atoms or ions in the ground state are heated to high temperatures, some electrons may absorb enough energy to allow them to jump to higher energy levels. 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.
Teaching notes and student guide for doing flame tests. Ramsey miller, menahga high school, menahga, mn, based on an original activity from the prentice hall chemistry (2005), flame tests, p142 1 students will review basic skills and safety procedures within a lab setting 2 students will observe similarities and differences of elements from the. Chemistry: flame test lab names: period: objective in this lab students will learn about atomic energy levels, emission spectroscopy, and flame tests for element. 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.
A flame test is an analytic procedure used in chemistry to detect the presence of certain elements, primarily metal ions, based on each element's characteristic emission spectrum. In5607 062007 catalog no ap5607 publication no 5607 flame test kit student laboratory kit introduction just as a fingerprint is unique to each person, the color of light emitted by metals heated in a flame is unique to each metal. Flame test for metals experiment 5 1 purpose perform the flame tests used to identify several metallic elements the solutions used in this lab contain.
Ibd chemistry - flame test practical aim: to test and observe the colour(s) emitted by various metal salts when placed and heated in a bunsen burner. Burning metals reveal themselves from unexpected, awesome colors in a simple flame test pour a little powder to test into each small dish dip one end of a popsicle stick into the water to moisten it it helps to dim the lights in your lab so the colors are easier to see light the flame and place. A powerpoint presentation, designed to be used with the interactive whiteboard looking at flame tests. To become familiar with the transfer of energy in the form of quantum, students perform flame tests, which is one way chemical engineers identify elements—by observing the color emitted when placed in a flame.
