ABSTRACT: In this investigate unknown unions were identified by performing different flame tests on known substances. The substances identity was obtained by placing salt solutions of a metallic ion and observing the color of the emitted photon light.
INTRODUCTION: By placing atoms of a substance into a flame it can absorb brawn and jump into an excited state; called a quantum jump. After absorb energy and leaping into an excited state, the atoms return back to their sea captain ground state by emitting a photon of light. According to the right of conservation of energy the same amount of energy use to make the quantum jump is released when the photon light is emitted. The energy of each photon is mensural using the equation 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 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 ability to specify an unknown substance will be available.




PROCUDURE: Seven well 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 along 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 longing 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 every test of a solution the nichrome wire was...If you want to get a full essay, order it on our website: Orderessay
