Part One (Flame Test): 1. Create and complete a data table for Part One of the lab. It should include the name of the element (or unknown) examined and the color of the observed flame SOLUTION | NAME | COLOR | KNOWN 1 | BARIUM | GREEN | KNOWN 2 | CALCIUM | RED | KNOWN 3 | SODIUM | ORANGE | KNOWN 4 | RUBIDIUM | PURPLE | KNOWN 5 | POTASSIUM | BLUE | KNOWN 6 | LITHIUM | VIOLET | UNKNOWN 1 | SODIUM | ORANGE | UNKNOWN 2 | POTASSIUM | BLUE |
1. Identify each unknown from Part One of the lab and briefly explain why you identified each unknown as you did. Unknown 1 was Sodium, as it burned with the same colored flame as the sample of Sodium, and Unknown 2 was Potassium, as it's flame was concistent with the flame test results of Potassium.
Part Two (Spectroscopy): 1. Create and complete a data table for Part Two of the lab. It should include the name of the element, the colors, and the wavelength values of the observed lines. | Hydrogen | Helium | Sodium | Neon | Mercury | 1 | purple / 413 nm | blue / 498 nm | yellow / 579 nm | purple / 421 nm | purple / 413 nm | 2 | blue / 441 nm | bluegreen / 509 nm | yellower / 586 nm | teal / 513 nm | blue / 497 nm | 3 | green / 512 nm | yellow / 589 nm | yellowest / 595 nm | green / 522 nm | green / 537 nm | 4 | gryellow / 539 nm | red / 691 nm | | greener / 526 nm | gryellow / 551 nm | 5 | yelgreen / 549 nm | redder / 735 nm | | yellow / 575 nm | yellow / 569 nm | 6 | yellow / 576 nm | | | yellower / 581 nm | red / 675 nm | 7 | red / 656 nm | | | reddish / 698 nm | redder / 692 nm | 8 | redder / 681 nm | | | red / 706 nm | reddest / 705 nm | 9 | reddest / 699 nm | | | redder / 719 nm | | 10 | | | | reddest / 745 nm | |
2.Describe the line spectrum of the star. Give the color and wavelength value of the five brightest lines in the spectrum.
The line spectrum of the star spans from purple to red, and contains several bright lines.
