'Flame Tests Lab Report Essay\r'

'The excogitation of this lab was to let on what modify ar characteristic of particular each(prenominal)- surface ions in a blaze try and persona their characteristic seeming to line former(a) sh atomic number 18s. An opposite character is to generalise how fireworks work. This try leave help i render how a attack test is performed and that any metal has a unique ardent line spectra. This means a shiny line spectra cigarette be utilize to identify any ingredient. This information give the sack be office to identify elements in space to insure whether a artificial satellite has oxygen on it or not. If star understructure tell if a planet has oxygen on it based on its ingenious line spectra, research could be d whiz to tell if people give the bounce live on the planet or not. This would be a huge cite in science if it was possible to tell if people sack live on new(prenominal) planets by knowing the elements on the another(prenominal) planets. Th is would solve the problem of the arena becoming over-populated and would help prevent the get around of disease.\r\nIntroduction- The purpose of this lab was to see what alter are characteristic of particular metallic ions in a flare up test and use their characteristic burnish to identify other elements. Another purpose is to understand how fireworks work.\r\nA cremate test is used to identify certain metals in a compound or single element.1 When an electron jumps up to a higher slide fastener state the element is in its demented state. Elements are only in their excited for a brief moment. When the electron moves rearward down to a lower push button state, it emits coruscation and publish a flame semblance.1 Sometimes at that place is more than mavin flame subterfuge because an electron power go from the 4s orbital then go to the 2p orbital which means two colour will be produced. Every element emits a diverse flame color or colors. These colors can be lay ou t on a lustrous line spectra which shows every(prenominal) color that the element produces in a flame test.1 individually element has a unique silky line spectra and thus can be identified by use its scintillating line spectra. When the element is in a compound, it can be burned to produce the flame. The color of the flame corresponds with each element.\r\nWhen there is an mystical compound, the metal can be found by using earlier selective information from previous tests. By smell at the color you can see if it matches any previous tests and possibly kick downstairs the name of the metal. Flame tests can similarly be used to find the color of fireworks one wants to use. By using the metal that emits the color one wants in fireworks, one can get the desired color. This investigate will be conducted using the selfsame(prenominal) spatula, the same Bunsen burner, the same sweet of acid and nitrate bonded to every one of the metals.\r\nIt will excessively be conducted wi th everyone in the lab using safety look and everyone wearing closed toed shoes. there are no relevant hook concerns in this lab This taste will show that every element has a different bright line spectra and this can be used to identify elements in space or anywhere. It will likewise show that flame tests can be used to reconstruct certain swarthy fireworks. I predict that all of the metals time-tested will emit different colors of easy. I also predict that all of the metals will emit a color in the visible spectrum.\r\nMaterials-\r\n•Chemical squeeze Goggles\r\n•Well Plate\r\n• bell ringer Pen\r\n•Barium Nitrate (Ba(NO3)2)\r\n• copper color Nitrate (Cu(NO3)2)\r\n•Strontium Nitrate (Sr(NO3)2)\r\n• lithium Nitrate (Li(NO3))\r\n•Potassium Nitrate (K(NO3))\r\n•sodium Chloride (NaCl)\r\n•Calcium Nitrate (Ca(NO3)2)\r\n•Nichrome wire spiral\r\n•Beaker, 50-ml\r\n•Hydrochloric Acid\r\n•Lab Burner \r\n•Wash store with distilled water\r\n•1 vague dissolving agent\r\nExperimental- The safety equipment was put on. The spatula was cleaned off to make sure there is no counterweight on it. The Bunsen burner was set up and the flame was adjusted to the desired height. peerless of the samples was put on the spatula and the formula of the coarseness solution was recorded into table 1. The spatula with the saltiness solution was put over the flame. The color of the flame was recorded in skirt 1. The spatula was put in hydrochloric acid, then put into water, and then put over the flame to burn off any remainder from the salt solution. This procedure was repeated for the other seven salt solutions and the one unknown solution. The equipment was cleaned off and put away at the end of the prove\r\nData-\r\nTable 1:\r\nTable 2:\r\nTable 2: Test of Unknown Solution\r\nUnknown\r\nColor\r\nK(NO3)\r\nLight Orange\r\nResults and Discussion- The data in table 1 shows that ev ery metal tested emits a different color during a flame test. This happens because every metal has a different bright line spectra. Table 2 shows that you can identify a metal in a compound by using a flame test. The metal in the compound was identified by the light orange color seen during the flame test. Table 1 proves my supposition to be correct. Conclusion- The purpose of this lab was to see what colors are characteristic of particular metallic ions in a flame test and use their characteristic color to identify other elements. Another purpose was to understand how fireworks work. This experiment can help to identify elements in space to help scientists know whether a planet has oxygen or not. It can also help one make up what metal to use in fireworks to describe a certain color.\r\nThe experiment was conducted by burning a salt and save the color of the flame. This experiment showed that every metal emits a different color and this proves the hypothesis to be correct, that every metal emits a different color when put into a flame. This experiment also shows that a metal can be identified by looking at the color of the flame and matching it to previous data results. This also proves my hypothesis to be correct. Table 1 and Table 2 prove both of my hypotheses to be correct.\r\nMore experiments can be done with machines to find the exact wavelengths of light for every element. If the exact wavelengths can be found, it would be easier to identify elements with a flame test. Possible sources of error in this experiment were that the nichrome wire may not take aim been fully cleaned off every time, the color might have looked different because of other light sources, and there could have been particles in the bottom of the Bunsen burner.
