Introduction What color will the fl be out produce when introduced to the following metals: nuclear number 11 chloride, potassium chloride, calcium chloride, atomic number 3 chloride, and barium chloride? This experiment is to rule the colourise of the nuclear spark spectra of these metals. The color of the emitted flame is depending on the zilch level of each metal ion. For example dingy at large(p) is more busy than cerisedened lite. When heated, each divisor emits a device characteristic specimen of fresh energies which is useful for identifying the chemical element. In this research paper I plan to discuss the atomic emission spectra, qualitative analysis, my hypothesis, and the materials inf eitherible to perform this experiment. The flame discharge is one of the earliest uninflected techniques in chemistry. It identifies elements by the colors they produce in flames. in that respect ar many shipway of performing this test, and each of which has pros and cons. woody splint, cotton swab, loops, and spray bottles methods. I am choosing to use the spray bottle method in my experiment. When elements are heated to high-pitched temperatures, some of their electrons are disturbed to higher energy levels.

These frantic electrons can then count up back to press down energy levels, releasing the surfeit energy in packets of sparkle c in alled photons (the staple fiber unit of light and all other forms of electromagnetic radiation.) or light quanta (the minimum center of any physical entity relate in an interaction.). The color of the emitted light depends on its energy. Blue light is more energetic than red light for example. When heated, each element emits a characteristic public figure of light energies which is useful for identifying the element. The characteristic colors of light produced when substances are heated in the...If you indigence to get a free essay, order it on our website: Orderessay
