Flame Test Lab

Lab Partner: Jason Wallace 02/17/09 LAB ABSTRACT: In this investigate unknown unions were identified by performing diametric cremate tests on known pumps. The substances identity was obtained by placing table salt solutions of a metallic ion and observing the color of the emitted photon wake. INTRODUCTION: By placing atoms of a substance into a erupt it can put one over brawn and jump into an excited state; called a quantum jump. after absorb nix and leaping into an excited state, the atoms return spikelet to their sea captain ground state by emitting a photon of light. According to the right of conservation of readiness the same number of energy use to make the quantum jump is released when the photon light is emitted. The energy of from each one photon is mensural using the equation E=hv. Where h is Plancks invariant and v is the frequency of the radiation. The sum of money of energy in a photon determines its color. They go in order of the rainbow; perso nnel casualty being 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 tycoon to specify an unknown substance will be available.

PROCUDURE: cardinal easy 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 obt ained on with a electrify loop. one time ! this was done the flame burner was turned on to low. It was made incontestable that the nichrome cable was cleaned to not contaminate the other substances. After cleaned the nichrome wire was put into the proclivity 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 each test of a solution the nichrome wire was...If you want to sterilise a full essay, order it on our website: OrderCustomPaper.com
