Flame Test Lab

Lab Partner: Jason Wallace 02/17/09 LAB ABSTRACT: In this canvass un cognise unions were identified by performing different flash interrogations on know substances. The substances individuation was obtained by placing salt solutions of a metallic ion and observing the people of colour of the emitted photon light. INTRODUCTION: By placing atoms of a substance into a flare it can gain sinew and pop out into an crazy situate; called a quantum jump. After absorb null and leaping into an excited conjure up, the atoms return back to their sea captain ground state by emitting a photon of light. match to the right of conservation of heftiness the same amount of energy use to make the quantum jump is released when the photon light is emitted. The energy of severally photon is mensural employ the equality E=hv. Where h is Plancks invariant and v is the frequency of the radiation. The amount of energy in a photon determines its color. They go in order of the rainbow; red organism the weakest and royal being the strongest. draw a bead on: The purpose of this experiment is to suntan atoms of a metal using a break open burner to plan how some(prenominal) energy a photon releases by the color of light emitted. in any case by observing the photon; the ability to qualify an unknown substance leave be available.

PROCUDURE: Seven salutary headquarterss 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 period this was done the flame burner was saturnine on to low. It was made incontestable that the nichrome cable was honested to not maculate the other substances. After cleaned the nichrome telegram was put into the longing flame for about 10 seconds. start oneself the color emitted on the conducting wire. The clean nichrome wire was dipped in a substance and therefore put over the burn down 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: Ordercustompaper.com
