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

Photometry Like all waves‚ light carries energy. The section of the optics‚ which are considered energetic characteristics of light in its broadcasting‚ distribution and interaction with a substance called Photometry. 1. Flow of light energy - energy transmitted through a surface per unit time. For example‚ the pupil of the eye glass window. If a body absorbs light fell on it‚ its internal energy increases‚ and thus its temperature increases. By changing temperatrata judge the flow of light

How does the chemical being burned affect the color of fire? Why do you think each fire burns a different color? The colors of the flames are are due to the different chemicals and substances. The bright yellow-orange of most wood fueled flames is because of the sodium‚ and when it’s heated‚ it emits the glow of the fire. The blue in some wood-fueled flames is because of the carbon and hydrogen emit a blue and purple aura. How are the colors produced by a chemical when it burns related to the atomic

Lab 1: Flame Test 11 Chemistry‚ university Preparation Conducted: September 20th‚ 2010 Purpose: To observe‚ and create a chart of the colours produced when solutions of known metal compounds are heated to high temperature. Question: What colours are produced when different metallic compounds are placed in a flame‚ and why this happens? Hypothesis/Prediction: Different salts will produce different colours when placed in a flame‚ due to the fact that each element has a different

Flame Test Lab Introduction/Purpose: When a certain amount of energy is supplied within an atom‚ the electrons of that atom begin to move up the levels of electron configuration. This level of energy is called a quantum. The object of this experiment was to examine the movement of electrons up and down energy levels through the use of given elemental substances. With heat supplying a large amount of energy‚ the properties of the elements caused them to give off a certain color or tone of

I then lit the handy wick to keep a flame burning. I soaked a cotton swab in the first chemical and moved the cotton swab in and out of the flame rapidly to see the flame color change

Timothy Johns Christian Howard Wan Huang 10/18/12 Flame Test Lab Introduction Spectroscopy is the study of the electromagnetic radiation emitted or absorbed by atoms and molecules. These studies are very helpful in determining an unknown element‚ given the fact that all elements burn a different color. The flame colors vary because of the different amounts of energy the elements give off. This lab is made for the learner to determine the identity of two unknown elements. Hypothesis If

Investigate Flame Colors of Different Cations When they were heated by Fire. & Testing changes of cations using sodium hydroxide (NaOH) aqueous Aims & Objectives Different characteristic cations will form different colors when they are burned or added base. In these two experiments‚ scientist took some sample of barium hydroxide (Ba (OH) 2·H2O)‚ ferric chloride (FeCl3·6H2O)‚ copper chloride (CuCl2· 2H2O)‚ calcium chloride anhydrous (CaCl2)‚ potassium carbonate crystal (K2CO3· 2H2O)‚

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
