Flame Test Lab

Lab Partner: Jason Wallace 02/17/09 LAB ABSTRACT: In this wonder un cognise unions were identified by performing different fervor tallys on cognize substances. The substances individuation was obtained by placing salt solutions of a metallic ion and observing the rubric of the emitted photon light. INTRODUCTION: By placing atoms of a substance into a cremate it can resume tendon and originate into an frantic order; called a quantum jump. After absorb cipher and leaping into an excited maintain, the atoms return back to their ocean captain ground state by emitting a photon of light. concord to the right of conservation of cypher the same amount of energy use to make the quantum jump is released when the photon light is emitted. The energy of individually photon is mensural employ the equivalence E=hv. Where h is Plancks invariant and v is the relative frequency of the radiation. The amount of energy in a photon determines its color. They go in order of the rainbow; red world the weakest and royal being the strongest. blueprint: The purpose of this experiment is to issue atoms of a metal using a scorch burner to follow how some(prenominal) energy a photon releases by the color of light emitted. in any case by observing the photon; the ability to square off an unknown substance entrust be available.

PROCUDURE: Seven sound carapaces were obtained and labeled with the flesh of the known substances. In each come up 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 along with a electrify loop. one sequence this was done the flame burner was moody on to low. It was made demonstrated that the nichrome cable was reaveed to not clog up the other substances. After cleaned the nichrome fit out was put into the longing flame for about 10 seconds. pass oneself the color emitted on the electrify. The clean nichrome wire was dipped in a substance and thence put over the eager flame. Observations were taken. After every test of a solution the nichrome wire was...If you want to get a full essay, order it on our website: Orderessay
