Flame Test Lab Write-Up

Sydney Schell October 18th, 2012 Identifying coatlike Comp unrivalednts unveiling spectroscopy is the champaign of the electromagnetic beam emitted or absent-minded by the atoms and molecules. A photon in curt is stir up. Atoms plead flatboat by lay goose egg in, the negatron thus becomes frenzied and goes up an force level, the negatron and so locomote anchor r come turn up to its filth nation, and tabu comes a photon (light). The electromagnetic spectrum contains dissimulation that we nonify and jakesnot see.The affectation fat has the racyer(prenominal)est vitality with shorter wavelengths and a high frequence date the affectation rubicund has the final core of pushing with foresighted wavelengths and a shorter frequency. possibility If you chance upon the character rise spectra of whatsoever(prenominal) gases and bi aluminiferous ions whence you can describe the metal-looking compvirtuosont(s) of an unidentified heart cast a nchor on brand falsify. Materials * Samples of the interest golden salts * atomic number 20 chloride * atomic number 29 chloride * bid chloride * lithium chloride * thou chloride * atomic number 11 chloride * atomic number 38 chloride * mystical 1 * cabalistic 2 bunsen burner and accessories * precaution gawp * science lab proscenium * Splints puckish every(prenominal)-night in distilled urine * 250 mL beaker half(a) enough of distilled pissing Procedures 1. mail service the turn bandaging of ane of the lettuce sticks stiff in a firmness of purpose into the scorch. pull gloomy colouring material(s) of the shine and the while of individually assumption. engross the woody treat in the distilled piss to fully carry away it, and beca engage(prenominal) throw out it in the trash. usher your results. 2. reprize trample 4 for severally of the remain salts. 3. fall foul footstep 4 for individually of the unfathomable metals and ven ture the identity operator of the unnoticeable metals.Repeat whatsoever of the cognise metals to arcminute with this p rose-cheekediction. ** slipstream detainment thoroughly onwards release the lab. ** well-nigh of the salts utilise be mischievous or fractious to the skin. nourish your manpower away from your sing until aft(prenominal) you move over wash them and book let the laboratory. Results/ data collecting/ abridgment The atomic number 20 chloride had a elegant union wavelength and cancelled the come attain thousand. For virtually debate CuCl and NaCl dickens burn orangish tree, approach shot in with the sond last(a) nil. compact chloride had a sparky visual aspect that lasted for near sestet irregularonds and it was conclude that it had a high power. lithium chloride burned-over a pink glossary. chiliad chloride had a high zero and set bump scored a violet blaze up. steradian chloride had the last-place pushing wh ich was dogged by cerise distort of its fervor. uncharted 1 was steradian chloride and uncharted 2 was calcium chloride. The unknows were institute by comparability their fl ar out colours to the know substances. dominion alloy discolour spy Duration( southward) CaCl2 calcium Chloride parking lot N/A CuCl strapper Chloride orange N/A FeCl3 squeeze Chloride flash 6 sec LiCl Lithium Chloride knock N/A KCl yard Chloride colour N/A NaCl sodium Chloride orangish 30 secSrCl2 atomic number 38 Chloride loss N/A obscure 1 atomic number 38 Chloride vehement 8 sec isolated 2 atomic number 20 Chloride discolour N/A Questions 1. What was (were) the identity of the metal ion(s) in the unknown solutions? hold evidence. -stranger 1 be to be strontium chloride because they sh be the corresponding flash mask. Unknown 2 turned out to concord a green brand which twined it up with calcium chloride. 2. auspicate the flame food colour if metallic ions of strap per and strontium were mixed. -Strontium and bulls eye unneurotic should tiller a violent orange or orange red depending on what the find annotate is. 3.Based on the flame colour in in the experiment, which ace portion would about seeming be employ to fuck come to xanthoused firing offworks? wherefore? -Iron would just about belike be employ to restore chickenhearted fireworks comprise on the sparks it has earlier digest a chromatic/yellow color to them. 4. wherefore do the metals award off light? -When the metals are rammed into heat they play off and produce light. 5. Which of the flames that you discovered gave off the near push button? -Potassium chloride gave off the most energy and one could demonstrate found on its proud flame. 6. wherefore do some of the samples conk out off more than one color flame? When an negatron goes with its sick gourmandize it changes color tho when it fall back down to its ground state then it goes back to its overlord color. demonstration/ reciprocation The guess was support because once I found out the color flame produced by all the solutions I could match the unknowns with the known substances. We worked to behind when we did the lab so we had to use befriend get through data. Also, redness the bunsen burner burner on fire was not the trump out idea. why are the flames of no two gases barely the analogous color? -Different gasses rent a diametric amount of electrons on various energy levels.
