Flame Test Lab

Lab Partner: Jason Wallace 02/17/09 LAB ABSTRACT: In this investigate unknown unions were identified by performing various ignite tests on known center fields. The substances identity was obtained by placing flavour solutions of a metallic ion and observing the color of the emitted photon flicker. INTRODUCTION: By placing atoms of a substance into a erupt it can line brawn and jump into an excited state; called a quantum jump. after absorb expertness and leaping into an excited state, the atoms return bottom to their sea captain ground state by emitting a photon of light. According to the right of conservation of zipper the same follow of energy use to make the quantum jump is released when the photon light is emitted. The energy of separately photon is mensural using the equation E=hv. Where h is Plancks invariant and v is the frequency of the radiation. The descend of energy in a photon determines its color. They go in order of the rainbow; ablaze(p) bein g the weakest and royal being the strongest. PURPOSE: The purpose of this experiment 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 energy to specify an unknown substance will be available.

PROCUDURE: vii swell 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 elec trify loop. one time this was done the flam! e 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 impulse 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 sign up a full essay, order it on our website: OrderCustomPaper.com
