Here you can order a professional work. For more information on these offerings, select a testing option. Or you could guess whether it is the cation (the positively charged metal ion) or the nonmetal anion that is responsible for the different colors. The characteristic colors observed are due to emitted electromagnetic radiation from the excited metal cations. Whether or not a white precipitate formed was recorded. Flame test lab report. ... ... test, the reagent was a yellow-orange color. ... metal ions, based on the color the flame that appears along with it when it’s heated. The green color denotes the presence of the element boron (B) which you’d expect in boric acid. Our Lady of Fatima University. The Flame test involves exposing the compound to a flame and identifying the compound by the flame color produced. Testing for ions - flame tests The Group 1 elements in the periodic table are known as the alkali metals . Control ?? The flame test is an analytical chemistry method used to help identify metal ions. This lab allows students to practice these techniques and identify the different metal ions. Lab 4.1b Flame Tests Revised: 2019-09-25 Chemistry I/H BACKGROUND Why do we see colors in a flame test? The Benettis want your company to identify the compound in ... More experiments can be done with machines to find the exact wavelengths of light for every element. Conclusion- The purpose of this lab was to see what colors are characteristic of particular metallic ions in a flame test and use their characteristic color to … Chemists are often required to test samples to find out if they contain specific ions or compounds. Flame Tests By: Jordan Anthony, Zack Balog, and Evan Degraw Regents Chemistry class, Union Springs High School, 4th period January 19/2015 The purpose of this lab was to see what colors are characteristic of particular metallic ions in a flame test and use their characteristic color to … Every element has a signature emission spectrum that can be used to differentiate between one element and another. I am writing a lab report on flame test and one of the questions ask "In the flame tests, chloride salts of the various elements were used; how do we know that the colors came from the metal cation rather than the chloride anion?" The flame test is used to visually determine the identity of an unknown metal or metalloid ion based on the characteristic color the salt turns the flame of a Bunsen burner. The identification of an unknown will also be performed by means of its own flame test. Flame Test Lab. Leanna_999. This can be very handy if you're a crime scene investigator, or a high school chemistry student trying to pass an exam. Comments. This preview shows page 1 - 2 out of 3 pages. Background and Theory. Test. LAB REPORT TEMPLATE – Use this template for all lab submissions Title: Flame Tests of Metal Ions Purpose/Introduction: This lab was done in order to observe the different colors that metal ions let off when placed over a flame. When metal salts (ionic compounds) are heated in a Bunsen burner flame, the metal gives off a characteristic color. The electrons in an atom occupy different energy levels, as you know. Flame Test Lab Objective In this lab students will learn about atomic energy levels, emission spectroscopy, and flame tests for element identification. Lab: Flame Tests Note for Teachers : Showing the NOVA film about fireworks (titled Fireworks!) Created by. Flame Test Lab . We will be using the ... All Papers Are For Research And Reference Purposes Only. Share. The test involve putting sample element and see what color appears. Q: When a compound is emitted through heat how can you tell if it is a non-metal or metal ion that is responsible for the color change? Lab report - Experiment #1: Flame Test Experiment #1: Flame Test. Flame tests and chemical tests are used to detect and identify ions in samples. When a salt is dissolved in water, the free anion will be present in the aqueous solution. Flame Test Lab. Ion Negative Ion Flame test color What ion causes color? When the element is in a compound, it can be burned to produce the flame. Calprotectin; Pancreatic Elastase; Contact. Test the different metal salt solutions in a hot flame and observe the characteristic color given off by each excited atom and to identify the metal ion present in one unknown metal salt solution. Move to station 2 for the next compound. Flame Test of Ions, including Li, Na, K, Sr, Cu, and an unknown. Flame Tests By: Jordan Anthony, Zack Balog, and Evan Degraw Regents Chemistry class, Union Springs High School, 4th period January 19/2015 The purpose of this lab was to see what colors are characteristic of particular metallic ions in a flame test and use their characteristic color to … As well as to identify unknown metallic ions by means of its flame test.
