Flame Test Lab

Lab Partner: Jason Wallace 02/17/09 LAB ABSTRACT: In this investigate unknown unions were identified by performing variant fervency tests on known stubs. The substances identity was obtained by placing common salt solutions of a metallic ion and observing the color of the emitted photon illume. INTRODUCTION: By placing atoms of a substance into a firing it can wage brawn and jump into an excited state; called a quantum jump. later on absorb thrust and leaping into an excited state, the atoms return backwards to their sea captain ground state by emitting a photon of light. According to the right of conservation of heftiness the same sum up of energy use to make the quantum jump is released when the photon light is emitted. The energy of each(prenominal) photon is mensural using the equation E=hv. Where h is Plancks invariant and v is the frequency of the radiation. The gist of energy in a photon determines its color. They go in order of the rainbow; departu re being the weakest and royal being the strongest. PURPOSE: The purpose of this sample is to burn atoms of a metal using a flame burner to see how some(prenominal) energy a photon releases by the color of light emitted. in any case by observing the photon; the power to specify an unknown substance will be available.

PROCUDURE: vii salubrious plates were obtained and labeled with the flesh of the known substances. In each well plate level a small amount of known substances into the well plate. persona a different well plate for each substance. A beaker with 10mL of 6.0 M HCL solution was obtained on with a electrify loop. one time this was done t! he flame burner was turned on to low. It was made incontestable that the nichrome cable was cleaned to non contaminate the other substances. After cleaned the nichrome wire was put into the inclination flame for about 10 seconds. find oneself the color emitted on the wire. The clean nichrome wire was dipped in a substance and then put over the burning flame. Observations were taken. After any test of a solution the nichrome wire was...If you want to arrive at a full essay, order it on our website: OrderCustomPaper.com
