Title: Flame Test Aim: To determine the cation in each of the unknown substance X‚ Y and Z by observing the flame colour of different metal compounds. Introduction: A distinctive feature of many s-block metals is their ability to produce flame colours. At temperature of a Bunsen flame‚ a compound will decompose to give gaseous atoms of its constituent elements. When an electron in the gaseous atom absorbs energy from the flame‚ it will move from an orbital with lower energy to

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 identify other elements. Another purpose is to understand how fireworks work. This experiment will help one understand how a flame test is performed and that every metal has a unique bright

Flame Test Lab Your company has been contracted by Julius and Annette Benetti. They are worried about some abandoned‚ rusted barrels of chemicals that their daughter found while playing in the vacant lot behind their home. The barrels have begun to leak a colored liquid that flows through their property before emptying into a local sewer. The Benettis want your company to identify the compound in the liquid. Earlier work indicates that it is a dissolved metal compound. Many metals‚ such as

11th D Flame Test Intro: The flame test is a procedure used by chemists to identify the presence of specified metal ions‚ based on the color the flame that appears along with it when it ’s heated. 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

INTRODUCTION Flame photometry‚ also referred to as ’flame atomic emission spectrometry ’ is a quick‚ economical and simple way of detecting traces of metal ions‚ primarily Sodium‚ Potassium‚ Lithium‚ Calcium‚ and Barium‚ in a concentrated solution. The process is an extension of the principles used in a flame test‚ with the main differences having more precision in the results‚ and the use of more advanced technology. This report focuses on the theory‚ applications‚ limitations and analysis of Flame Photometry

Flame Tests 12.01.2010 19.01.2010 Introduction 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. 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 element is then said to be in the “excited state”. This excited configuration is unstable‚
Premium Potassium Atom Photon
different metals have different characteristic flame test colours? The photons emitted during the test precisely match the quantum energy difference between the excited state and the ground state. For different elements the spacing between the ground state and the higher energy levels is different. So different elements have different flame test colours. 2. Most salts contain a metal and a non-metal. Look at the compounds we tested and determine whether it is the metal or the non-metal that is

Date: 20/03/13 Flame Test – Investigating Compounds Aims To identify the presence of a relatively small amount (ie low concentration) of a metal ion in a compound. Method 1. Clean a platinum or nichrome wire by dipping it into concentrated hydrochloric acid. 2. Hold the platinum or nichrome wire at the hottest or blue part of a non-luminous Bunsen flame. 3. Repeat until the wire does not produce any colour in the flame (note: do not touch the wire‚ as salt in sweat will produce

Flame Test Lab Question: When a compound is placed in the flame of a burner‚ what happens to the color of the flame? Hypothesis: When the compound is placed in the flame‚ the flame changes color depending on the chemical compound. When they’re heated‚ they gain energy and changed color sometimes. Safety Requirements for this Lab: Wear goggles at all times. If you want to remove them to write in your notebook you may sit at a table in the center of the room. When you sit down remove them
