The intent of this lab was to see what colourss are characteristic of peculiar metallic ions in a flame trial and utilize their characteristic colour to place other elements. Another intent is to understand how fireworks work. This experiment will assist one understand how a flame trial is performed and that every metal has a alone bright line spectra. This means a bright line spectra can be used to place any component. This information can be used to place elements in infinite to state whether a planet has oxygen on it or non. If one can state if a planet has oxygen on it based on its bright line spectra. research could be done to state if people can populate on the planet or non. This would be a immense progress in scientific discipline if it was possible to state if people can populate on other planets by cognizing the elements on the other planets. This would work out the job of the universe going over-populated and would assist forestall the spread of disease.

Introduction- The intent of this lab was to see what colourss are characteristic of peculiar metallic ions in a flame trial and utilize their characteristic colour to place other elements. Another intent is to understand how fireworks work.

A flame trial is used to place certain metals in a compound or individual component. 1 When an negatron jumps up to a higher energy province the component is in its aroused province. Elementss are merely in their excited for a brief minute. When the negatron moves back down to a lower energy province. it emits visible radiation and bring forth a fire colour. 1 Sometimes there is more than one fire colour because an negatron might travel from the 4s orbital so go to the 2p orbital which means two colourss will be produced. Every component emits a different fire colour or colourss. These colourss can be put on a bright line spectra which shows every colour that the component produces in a flame trial. 1 Each component has a alone bright line spectra and therefore can be identified by utilizing its bright line spectra. When the component is in a compound. it can be burned to bring forth the fire. The colour of the fire corresponds with each component.

When there is an unknown compound. the metal can be found by utilizing old informations from old trials. By looking at the colour you can see if it matches any old trials and perchance happen the name of the metal. Fire trials can besides be used to happen the colour of pyrotechnics one wants to utilize. By utilizing the metal that emits the colour one wants in pyrotechnics. one can acquire the coveted colour. This experiment will be conducted utilizing the same spatula. the same Bunsen burner. the same sort of acid and nitrate bonded to every one of the metals.

It will besides be conducted with everyone in the lab utilizing safety goggles and everyone erosion closed toed places. There are no relevant waste concerns in this lab This experiment will demo that every component has a different bright line spectra and this can be used to place elements in infinite or anyplace. It will besides demo that fire trials can be used to do certain coloured pyrotechnics. I predict that all of the metals tested will breathe different colourss of visible radiation. I besides predict that all of the metals will breathe a colour in the seeable spectrum.

Materials-

•Chemical Splash Goggles
•Well Plate
•Marker Pen
•Barium Nitrate ( Ba ( NO3 ) 2 )
•Copper Nitrate ( Cu ( NO3 ) 2 )
•Strontium Nitrate ( Sr ( NO3 ) 2 )
•Lithium Nitrate ( Li ( NO3 ) )
•Potassium Nitrate ( K ( NO3 ) )
•Sodium Chloride ( NaCl )
•Calcium Nitrate ( Ca ( NO3 ) 2 )
•Nichrome wire cringle
•Beaker. 50-ml
•Hydrochloric Acid
•Lab Burner
•Wash Bottle with distilled H2O
•1 Unknown Solution

Experimental- The safety equipment was put on. The spatula was cleaned off to do certain there is no residue on it. The Bunsen burner was set up and the fire was adjusted to the desired tallness. One of the samples was put on the spatula and the expression of the salt solution was recorded into Table 1. The spatula with the salt solution was put over the fire. The colour of the fire was recorded in table 1. The spatula was put in hydrochloric acid. so put into H2O. and so put over the fire to fire off any residue from the salt solution. This process was repeated for the other seven salt solutions and the one unknown solution. The equipment was cleaned off and set off at the terminal of the experiment

Data-

Consequences and Discussion- The informations in table 1 shows that every metal tested emits a different colour during a flame trial. This happens because every metal has a different bright line spectra. Table 2 shows that you can place a metal in a compound by utilizing a flame trial. The metal in the compound was identified by the light orange colour seen during the flame trial. Table 1 proves my hypothesis to be right. Conclusion- The intent of this lab was to see what colourss are characteristic of peculiar metallic ions in a flame trial and utilize their characteristic colour to place other elements. Another intent was to understand how fireworks work. This experiment can assist to place elements in infinite to assist scientists know whether a planet has O or non. It can besides assist one find what metal to utilize in pyrotechnics to portray a certain colour.

The experiment was conducted by firing a salt and entering the colour of the fire. This experiment showed that every metal emits a different colour and this proves the hypothesis to be right. that every metal emits a different colour when put into a fire. This experiment besides shows that a metal can be identified by looking at the colour of the fire and fiting it to old informations consequences. This besides proves my hypothesis to be right. Table 1 and Table 2 prove both of my hypotheses to be right.

More experiments can be done with machines to happen the exact wavelengths of visible radiation for every component. If the exact wavelengths can be found. it would be easier to place elements with a flame trial. Possible beginnings of mistake in this experiment were that the nichrome wire may non hold been to the full cleaned off every clip. the colour might hold looked different because of other light beginnings. and at that place could hold been atoms in the underside of the Bunsen burner.
