Purpose: Find the composition of an unknown salt solution. Create an orbital diagram of Hydrogen. First, a spectrometer was tested. It was used to look at an incandescent light, and a continuous emission spectrum was observed, with wavelengths at all values ranging from red to violet. When it was used to look at a fluorescent light, lines were seen at the wavelengths (in nm): 610 – 8 (relative intensity) 590 - 4 545 - 9 490 - 1 435 - 7 Next, the spectrometer was used to look at a helium discharge tube. The following wavelengths were observed: 706 (nm) – 189 667 – 170 587 – 339 500 – 149 446 – 139 388 – 151

Each salt gives off a distinct emission spectrum. The salts tested in this experiment were NaCl, LiCl, KCl, CaCl, SrCl. The following results were obtained: NaCl (in nm): 588, 544, 611, 435 KCl: 435, 545 , 588, 611, 768 , 957 CaCl: 435, 487 , 533 , 588, 611 LiCl: 671 , 611, 541 SrCl 2 : 670 , 606, 683 . The values in bold are values that occur only with those specific salts. The other values are repeated
