Transition Metals and Coordination Compounds- Spectroscopy in Large Lecture Hall II

Spectroscopy for Large Lecture Hall II

Description: Half-filled containers of colored solutions are placed in front of a white light. The light is viewed through a diffraction grating. The absorption spectra of  the colored light can be seen and compared to the spectra of white light. Source: Journal of Chemical Education Year: 1988 Vol: 65 Page: 1006 Keywords: White light, Diffraction grating, Diffraction, Spectrum, Absorption Rating: Hazard: Low
  • Electrical shock hazard
  • Breakage hazard
  • Aquatic toxicity hazard
  • Acute toxicity hazard
Effectiveness: Good
  • Results are observable with guidance
  • Good connection from demo to course material
  • Good reliability
  • Moderate failure rate
  • Time to results is low
  • Mild effects are seen by audience
Difficulty: Medium
  • Accurate alignment required
  • Demos in which objects are passed out to students
  • Simple procedures
  • Careful handling of lamps required
  • Liquid level must be half-full in cuvette
Safety Precautions:
  • Use of UL approved three-prong and outlet
  • Gloves required when handling lamps
  • Absorbent material on hand
  • Sodium bicarbonate on hand
  • Prevent release of reagents to the environment
  • Avoid exposures to droplets and vapors
