What This Document Is
This document represents a completed lab experiment for CHM 100, Introduction to Chemistry at Bergen Community College, dated February 26, 2022. It details a student’s work on spectral analysis and flame tests, focusing on identifying elements based on their emission spectra and the colors produced when their chloride salts are heated in a Bunsen burner flame. It includes pre-lab answers and recorded observations from the experiment.
Why This Document Matters
This assignment is intended for students enrolled in CHM 100 who have completed the fifth laboratory experiment. It serves as a record of their experimental process, data collection, and analysis. Instructors use completed lab assignments like this to assess student understanding of atomic emission, flame tests, and spectral analysis techniques.
Common Limitations or Challenges
This is a *completed* student assignment. It demonstrates one student’s approach and results, and should not be used as a substitute for performing the experiment and drawing your own conclusions. It does not provide instruction on *how* to perform the experiment.
What This Document Provides
The document includes: answers to pre-lab questions regarding electron energy states and flame test principles; observations from spectral analysis of Hydrogen, Helium, Neon, and Nitrogen; a data table recording observations from flame tests of Potassium and Calcium; and an attempt to identify unknown substances based on flame color. This preview does *not* include the full experimental procedure, detailed spectral data, or a complete identification of all unknowns.
